Guys, what the fuck, really. What does it matter if your computer runs 1FPS higher than another one? If it can run it, what's the big deal?
The better = The more money it'll cost you and my only advise to give you is don't spend TOO much money in computers anyway. Perhaps within 2 months you want another hobby and there you are, with that ubersystem that you don't use anyway. Remember to buy what you need, not the best thing on the Market.
You don't buy a Ferarri just because you need to drive to work eh?
