When everything is tested out right, I'll know if I get 70fps a single 5870 on a i7 @3.8-4 ghz setup, at high settings, 2x aa 16x af, if not, then I'll have to use the 5970..
What I'm looking for is a minimum of 70 fps in all games using a video card at high settings, and chances are a 5870 won't suffice...some of you can't seem to tell the difference between 40fps and 70fps so you can stick to whatever frames you like, I personally like 70-120 fps while gaming at maxed out settings (AA filtering can be minimal). This test should hopefully give an insight to a lot of issues regarding this game.
Also, I don't think I have anything to lose in this situation..
From reading numerous reviews, I need a 5970, it's the sound decision for future-proofing.
On another note, does anyone know how to effectively guage fps max and min and average while gaming and have a program report that back to you?
