Thanks for all the previous input, and I think I have come up with a build. I just wanted some final confirmation on the compatibility! This is primarily a workstation with light gaming uses. (Maya 2011, Photoshop, After Effects)
I would love to be able to add multiple cards in the future, but then again that is what I planned for my current system and never managed to do so before the cards were pretty much obsolete.
I actually have a 520W power supply at the moment that I would love to be able to reuse.
I was going off of the Maya 2011 qualified hardware list, which is why I picked out that video card. However, scrolling down some more, I see that it is not that the GeForce ones were not recommended, but it was just that it hadn't been tested except with windows 7. So that concern is moot! Yay!
So, reduce the power supply (maybe just try with my current and order better if needed), and switch out the video card with: this one (the gtx 570) and call it good?
^ What is the make and model of the PSU that you have ? I would actually do a total rebuild with an Intel CPU... No am not an Intel or AMD fan, but would like to get the best what I can with the money I have,... If you are fine with Intel, then I could suggest 1 and am sure it would be significantly better than the AMD's also will stay within the same price range,...
The psu i have is from a case a friend had, he had to upgrade, and it was better than mine so i took it. This one i think.
From my research I am lead to believe that Maya favors AMD over intel, which is why I went that direction. However, I'm honestly not sure if it just a business arrangement between the two, or if there are significant performance differences. I can't really find information either way. If I could get more for the money I wouldn't mind going Intel. All Autodesk says is: Intel® Pentium® 4 or higher, AMD Athlon™ 64, AMD Opteron™ processor, AMD Phenom™.
Thank you so much gkay09. All the benchmark articles I could find were still using Maya 6.5 or so. Especially since I'm more concerned about viewport performance than rendering (I'm a rigger so I'll be rendering once in a blue moon), the intel i7 definitely looks like the way to go!
