Long load times is a problem.
And FPS in some games are a problem.
FPS I'm -sure- has to do with my CPU, because the 580 is a freaking boss.
Budget? Eh, no more than like 200-250$
What is your problem with your current system?
What is your budget?
A SSD is one of the better performance enhancers .
A second monitor is one of the most useful upgrades.
My guess is that AMD bulldozer will be like the current X6; good for the price, and good for multitasking, but not so hot for gaming.
