ok so money is really tight right now i only have a phenom 955BE cpu i have not played bf3 for over a month and i want to get a 1080p monitor and the 570 or 580 superclocked but people keep saying its gonna bottleneck the cpu i don't want to overclock it but what do u think what would be the best card for that cpu its only a month or two till i get some high end stuff so what do u think i should do.
If you're getting "high end stuff" in a month or two, I'd wait for a month or two to buy anything.
Tom's also has this helpful series of articles called "best graphics card for the money"... just check that and see what price point you want to buy in at.
For a title like battlefield 3, you probably won't see any bottleneck from the CPU (or at least, you'll see very little). Other less GPU demanding games will be slower because of the 955, but bf3 is very much GPU limited.
