I just been giving out same advice to someone, so will post it here too...
Why the 8200 over the q6600...ditch the Westerndigitals get Samsung 1TB's, everything else looks ok.
OK this quote was for audio workstations on a budget in the UK.

I put together a quad machine last year, paid 167 for 4 gb of ram, bought a more expensive mobo, about 150, and a 100 quid case, and a 700wattPSU (which if i did over again I would go for smaller Quieter one, as I dont have crossfire or SLI), so total with monitor was 1000, there was a test on 1066mhz ram, and they reckon for the extra cash vrs speed it was not worth it...so 800 is fine and 4gb will cost 50 quid, a decent 24in mon is no more than 250.
3TB of samsungs for 180 (hell jut get 4 of them at 70quid each), these drives are great, better than Raptor's (IMO), I had a mate who swore by Raptors, I used to think He was a ****, because they where only any good when everyone was on SCSI, these days sataII raided is fast.
I had a more expensive Mobo the ASUS IP35 PRO (or Abit)...I figured go for the best at the time, but it died after about 11 months....it was recomended, but anyway SCAN replaced it No Quibble. they have 3yr warranty on most stuff 24 Months on some.
I want another system, before HyperINF' but want to go with just a cheap 50 quid mobo. Stock cooler is fine, if not OC'd but this q6600 chip is great for overclocking upto 3.2Mhz.... but I don't feel the need to, its doing just fine for my needs.
it was available for 100 quid but its crept upto 150inc vat, Now the i7 is out the price should be dropping, but I want to get another before they drop it, I would hate to be forced to go i7 route.
The graphics I have is only radeon 2600, its fine, there's a lot of bullshit around about GFX cards...
ones to watch 1650, 1950, 2400, sapphire's, now I might get the piss taken out of me for recomending such lowly cards, NVidea would be nice for 3D, so an 8800, has been mentioned, cuda would be nice to have but I reckon it will still be a little while before it settles down???, but I was just reading an article about graphics cards the other day...I will have to dig it out for you.....

Anyway its all personal choice at the end of the day, hope it helps.
