for games, almost any modern cpu is enough. remember when they used to get smooth fps out of a p3 with a 6800GT in doom3? And they were saying you needed a fastass machine...
your cpu is more than enough. MORE than enough. you need to get rather high on resolution etc to reach a point where your cpu can't keep up. And even if you get a graphics card SO fast that your cpu can't keep up, you will be getting ridiculous fps, which means that even if you got a faster cpu to keep up with your graphics card, it wouldn't make much difference. look at benchmarks online. takes a little getting used to, that's all.
don't worry, i don't bite. ask jakg if you wanna know what kind of pre-built PCs they sell at shops...
did i drink too much coffee or something? anyway, goodnight all!
