How'd I buy new PC?

what's a good place to buy pre-built or custom-built PCs? I'd build one myself but I'm a big fucking n00b and dangerously prone to static electricity.

I'm looking to spend around $1200 for a new PC (to run Vista but mostly b\c of DX10). My only requirements for the new computer is to have 2GB of RAM and a Dual Core Duo 2 CPU (preferably greater than E6400). However, it seems I can't find any PC from retail or the usual online places (DELL, HP) with a CPU better than Core Duo 2 E6400 (looking for atleast e6600). Am I overdoing it with the CPU?

ok, looks like there's no easy way to get a good computer without having to do some research, though I wish there was a definitive guide for what to buy. But then, I'll probably wait for Vista to be released anyways...

I never really got the appeal of Macs, really. They look real sleek and it seems they can do every than a PC can now, but the price point and seeing how they have a monopoly on parts (correct me if I'm wrong) is a bit of a turn-off.
