I was finally able to install the 6870 (kinda old, but new to me) into my system earlier this week and I am happy with the performance that I am getting right now. My question is, when I get the money (this summer b/c I'll be working), what is the best graphics card that I can get before my cpu becomes a bottlekneck? This system is fine for me right now as I am just a casual gamer and in school, but I try to upgrade it when I can.
The 560's are phased out now. A 7970 is pushing it on that CPU of course it depends what games your playing. It should be able to handle a 7870 without any problem and perhaps a 7950. Then the Nvidia side of those cards the 660 and the 660Ti.
