Dont listen to amd fanbois, most of them dont have a clue as to whats the best hardware is.
Truth is AMD hasnt been competing with intel for 5 years, and all reports indicate that bulldozer cpu will be massive failure
If you have a Microcenter store in your area, you can pick up the best gaming cpu out there for 180 dollars, the 2500k.
Anyone not recommending a 2500k for gaming is a tool, kid, or hardcore fanboi.
Once you have a 2500k, video card wont matter much, since both amd(ati) and nvidia cards are great nowadays, and prices are good.
When your GPU bound you can lower detail settings so you get a good framerate,
when your cpu bound, youre screwed, game will run choppy and slow no matter what you do, even on lowest settings.
Intel cpus can take more heat, and are more durable
Intel cpus overclock much higher
Intel cpus are faster clock for clock
Intel cpus are far more energy efficent at both load, and idle
And for people that worry that supporting intel will lead to them charging very high prices in future,
this isnt a concern anymore with all the competition intel is facing from ARM, apple, tablets, and phones. They have to sell desktop cpus at very competitive prices, otherwise no one will buy them.
