I plan on buying a new video card this month, the budget is up to $400. The card will be used mostly for gaming. I am also willing to consider the AMD equivalents, 7950, 7970, R9 280x.
My specs are:
Core i7 940 at 2.93 GHz
6 GB Ram
500 Watt PSU (I know I will need to upgrade, I can take suggestions for this too)
I want a single card system, and I will be playing in 1920x1080. Also, can AMD cards be used for rendering in Blender?
Thanks for your advice.
