What would be the highest graphics card that I can pair with my cpu?

[gorebs24]

I have an a-8 5600k processor with a 700watt psu. I am currently using a 7850 1gb card with no problems. I get 50-70 fps on BF3 ultra and about the same on Tomb Raider. The whole 1gb thing is throwing me off. I have a 650ti 2gb card laying around too. I never got to returning it. Ha.

In the future, I will go with a better processor but this is my first one!

Thanks in advance.

you can easily pair a gtx 690 and even a 790(when it comes out) with your processor without any bottleneck.......
dont worry.....coz your present gpu is definitely gonna buy you at least 2 more years of satisfactory gaming......
