sagartotal3ds Posted April 21, 2009 Share Posted April 21, 2009 Hi, I am looking to buy a new system in coming month but have some problem in a decision. i am thinking to buy core i7 but not sure about which one i buy for my pc 920 2.66ghz or 940 almost 3ghz i relay want to know the real permanence deference between 2 of them please suggest.

mi75 Posted April 21, 2009 Share Posted April 21, 2009 I can't say which is better but I have my 920 clocked at 3.2Ghz and it renders all day and night no dramas on air. So you could go the cheaper 920 and do a slight overclock to outperform the std 940. my 2c Link to comment Share on other sites More sharing options...
sagartotal3ds Posted April 22, 2009 Author Share Posted April 22, 2009 Yes you are wright but what if i just buy an 940 and then overclock it. i think it will make lot of difference may be it can touch the 4 ghz but i still not get my ans Link to comment Share on other sites More sharing options...
AJLynn Posted April 22, 2009 Share Posted April 22, 2009 The difference between the chips is: -The speed in GHz -The price Overclocking is not an exact science and there can be no guaranntees as to how overclockable each system is. Link to comment Share on other sites More sharing options...
ihabkal Posted April 22, 2009 Share Posted April 22, 2009 don't get the faster cpu and overclock it, it is already hotter than the 2.66 no one does that, they usually get a slower cpu and overclock. spend the extra money on ram and get the 2.66, I would.

sagartotal3ds Posted April 23, 2009 Author Share Posted April 23, 2009 Well i understand the problem now but what if i had a good cooling system and cool atmosphere. I think i have to show my com conf so that every body can give there opinion in that. So this is my com configuration 1. Intel I 7 920 2.66 ghz,8 Mb Cache or 940 3ghz 2. Gigabyte GA-EX58-EXTREME Motherboard 3. Hard Disk Western Digital Raptor 10k Rpm 250 gb for booting 4. Hard Disk Western Digital 1TB sata2 for storage 5. Cooler Master's V10 for cpu cooling 6. Dvd RW : DVD Writer for movies 7. Ati Radeon 4870 HD 1 gb for smooth work 8. Cooler master S RC-1100 cabinet 9. power supply Cooler master Real Pro 1000 Watts 10. Ram 2 gb ddr3 1333mhz (total 12 gb) 11. Keyboard + Mouse Razer Lycosa Gaming Keyboard 12. Monitor TFT 22" View sonic VX 2235 may be 24" Please suggest, Link to comment Share on other sites More sharing options...
sagartotal3ds Posted April 23, 2009 Author Share Posted April 23, 2009 What about new xeon processors 5500 Series. i think thay are expensive Link to comment Share on other sites More sharing options...
ihabkal Posted April 23, 2009 Share Posted April 23, 2009 don'y get the 1000 watts power supply, I am not sure but I think 600 Watts will suffice but there are online calculators where you put your components and they tell you what you need to get. It will cost you more in electricity, waste energy, you will need a bigger UPS, just waste IMO. I tried going this route before and regretted it. everything else sounds sweet.

Monitor TFT 22" View sonic VX 2235 may be 24" Please suggest, Like mentioned above all chips will respond different to overclocking and I know people who have gotten significantly more than me with no problems but that's the best I could do with mine. As for cooling I would recommend the Noctua NH-U12P which I'm running plus I'm also running 4 x 120mm fans plus the 2x 120mm fans on the CPU cooler and I still struggle to keep the temps low during a burn test at 3.2ghz.

This is an interesting post I read the other week. Its long but worth reading. link to article I found it quiet interesting and it gave me a better understanding of why some run hotter or cooler etc....... and why some are worth more $$.

AJLynn Posted April 23, 2009 Share Posted April 23, 2009 Very interesting post. Thanks, Martin. I don't think it's appropriate to have a copy of somebody's article here in its entirety without attribution, so I'm going to do an edit and make it just a link.

sagartotal3ds Posted April 24, 2009 Author Share Posted April 24, 2009 Thanks MI75 it will help me a lot. So the conclusion is i need to buy 920 so that i can overclock it easily right? But is some body had a i7940 and he over clocked it and it performed cool ? I need to know. Thanks, Link to comment Share on other sites More sharing options...
AJLynn Posted April 24, 2009 Share Posted April 24, 2009 No. The 940 will be able to OC to a higher clock speed. While the 920 may OC more, in terms of the difference between its set frequency and the frequency it can hit, the 940 will hit a higher total speed. But, look, we're not OC experts here and the rest of the internet is full of OC experts. We mainly discuss computers to be used in architecture and CG business environments, and OC'ing is usually not appropriate to business environments. If you're talking about your home PC go find forums full of gamers who OC their i7's and see what they're doing. Link to comment Share on other sites More sharing options...
ihabkal Posted April 24, 2009 Share Posted April 24, 2009 overcloking is IMO not something you would do on equipment you use daily for work, it is better to have stable and reliable equipment. If you go this route, sooner or later you will push that cpu further than it can handle and you will fry it. power is addictive. Link to comment Share on other sites More sharing options...
Tim Nelson Posted April 24, 2009 Share Posted April 24, 2009 overcloking is IMO not something you would do on equipment you use daily for work, it is better to have stable and reliable equipment. If you go this route, sooner or later you will push that cpu further than it can handle and you will fry it. power is addictive. Maybe earlier on. But ever since the Core 2's and Quad Core's its been so easy to overclock, and they are designed to be overclocked. Its not the risk factor that it used to be.

sagartotal3ds Posted April 25, 2009 Author Share Posted April 25, 2009 Well thanks everybody thanks for every hing you share to find me a good pc and i respect the comment of the Senior moderator and will not talk about OC now but thanks for yours comments(ihakbal).

sagartotal3ds Posted April 25, 2009 Author Share Posted April 25, 2009 Ok one more Q graphic card which one is the best? NVIDIA GeForce GTX295 X2 ,or ATI Radion 4870 hd DDR5. Thanks, Link to comment Share on other sites More sharing options...
ihabkal Posted April 25, 2009 Share Posted April 25, 2009 Just now I am checking prices on the 4870, I have been a fan of Nvidia for years, but a few months ago I got a 3870, and I am seriously thinking about gettign ATI equipment from now on. it is cheaper, and I see it easier to understand what are the components of the parts you are buying. I find the Nvidia naming scheme complicated and I can't understand it. I would recommend the 4870 as I am going to buy one sooner or later, maybe Monday even. ABout the x2 cards they are great for games but not so much for Autocad and 3dsmax, so it is an additional cost that doesn't compute for us, besides they need more electricity and generate a lot more heat than single gpu cards. In the long run excessive heat in your box will shorten your equipment life. Link to comment Share on other sites More sharing options...
Jez(UK) Posted April 25, 2009 Share Posted April 25, 2009 I went for the i7 940 with 12gb of ram. I went for that on the basis that I'm not intending to overclock for the reasons given by others (i.e. I need reliability/stability) - I also felt that if I went down the road of overclocking, I'd be spending time 'tweaking' this and that rather than using my 'tools' to do actual productive work. I am also using the Noctua heatsink recommended by someone and I can't believe how cool my machine is compared to my previous one (dual xeon). My Xeon was always running way too hot. BTW, I bought my 940 on eBay (brand new) as it was going so cheap - literally the same price as a 920 sells for from a computer website (seriously). Also, my 2cents worth, I have a 1000w psu (Enermax) and have never regretted it. A PSU will run more efficiently if it isn't being pushed to it's limits and it'll also be one of the more futureproof items you can buy for a computer, most other things you end up upgrading. I believe my Enermax will last for years and will see 3-4 more upgrades in this current system. Also, if you are anything like me, you may wish to add more and more hard disks and that 1000w PSU will cope with that easily (as also it may if you decide for example to add a 2nd Graphics cards). As I said, just my 2cents. Good luck, Jez Link to comment Share on other sites More sharing options...
ihabkal Posted April 25, 2009 Share Posted April 25, 2009 may I ask if you have a UPS system or you don't need one where you live because the electricity is reliable? here we have daily blackouts, and rolling blackouts of 3 hrs every day. so a UPS is essential.

Jez(UK) Posted April 25, 2009 Share Posted April 25, 2009 I live in the South East of the United Kingdom and we don't usually have problems with electricity (touch wood!!) - maybe the odd lightening strike which has knocked the power out and fried the tv and telephones ! So I do have a good quality surge protector to protect the PC. When I used to live in Morocco however, yes a UPS would have come in very handy where sometimes the whole street would suddenly be without power (but then that was once in a blue moon so not a very frequent occurence).

ihabkal Posted April 25, 2009 Share Posted April 25, 2009 great. surge protection is a great idea, a lightning strike burned my $1500 LCD tv a couple of years ago. the dealer said it costs $400 to fix. Link to comment Share on other sites More sharing options...
sagartotal3ds Posted April 27, 2009 Author Share Posted April 27, 2009 OH Man that scares me i think i need to take a good ups also for supporting the electricity cut because in india i lived in a capital city but still we have to face the power cut for some time a whole day.
