Graphics Cards for Vray 2 and Twinmotion?

[Sketchrender]

I want to order a graphics card for Vray 2.0 GPU and TWinmotion , the up and comming new software?

I want to cover both so.

 

ASUS ENGTX470/2DI/1280MD5 - Graphics adapter - GF GTX 470 - PCI Express 2.0 x16 - 1.25 GB GDDR5 -

 

I was looking at the GTX 470.

 

I am on XP 64 on Dell precision 690 4gb ram.

 

Is that the best card for the money?

Would appreciate advise.

 

Thank you

Well, Twinmotion isn't out yet, there's just these demos so there's no way to give advice on what video card would be good for it. And separate the publicity from the reality - do you really want to spend money right now on a product you don't know anything about?

 

So, Vray 2.0. As it is right now you're looking at nVidia because they don't have ATI compatibility working yet. A 470 is a good one, the only concern I have is that with the new tech 1.25GB isn't actually a lot, so consider the 2GB version of the 460, or if you can wait a while, buy nothing now and wait for 2GB+ to become commonplace next year.

Here are the recommendations for TwinMotion2

 

Minimum configuration:

- Nvidia Series 9xxx or Radeon HD

Recommended configuration:

- Geforce 260 or higher or Radeon HD 4890

Well the GTX 460 (2GB version), 470 and 480 seem the obvious choices. ATI has more 2GB options but there's no word on the Vray/ATI compatibility front.

 

Still, I'll tell you what I tell everybody, don't buy hardware until your software plans firm up.

With NVidia making great cards in the GTX 4XX Series, is there any reason to drop an extra $500 +/- on a Quadro?

 

Would it be better to go with 2 GTX460's in SLI ?

 

( I blew $1000 on a FX1100 about 8 years ago and don't think I ever got the value out of it )

We have our cards all setup in SLI and it does provide a process boost. Some of these damn cards cost as much as an entire PC these days!

[AJLynn]

SLI is for the display. It's mostly for games though, Max doesn't see the same level of improvement. For Vray RT-GPU you don't need to SLI your cards but maybe it would help in Twinmotion - hard to say since it's still in closed beta, but if anybody were looking to buy two GPUs I don't see any good reason not to buy identical ones that can be SLI'ed (or Crossfired) should that become important.

Hi Phil,

 

If you interested I will be testing the 460 and 480 next week and once i've got the results i'll add them to the benchmark results I posted about last week. My gut feeling is that unless you have huge scenes that require 4GB + you'll be fine with the GTX range.

 

Vray 2.0 isnt out until December anyway, so there's plenty of time to see what provides the best solution.

I'd take Andrews advice and hold off until these things come out and you know what the memory requirements will be. The biggest problem GPU rendering has is the amount of available memory on the cards, with most machines having at least 4 gigs of ram these days your card is most likely going to need a similar amount. If you look at most of the demo's that Chaos has put out for GPU rendering you'll notice that all the scenes are extremely simple, I haven't seen one that I'd consider even close to having all the elements of a final rendering. I think in most cases you'll be able to use GPU rendering to a point but once you get there you'll have to switch to CPU rendering because of the memory limitations.
