cyberpowerpc.com if you have the cash... best custom pc place imo... i built my own...

go with the core i7 920, vista 64-bit, and as much triple channel memory as you can afford... go with the 1333 speed too as when you overclock, it scales up the best for the value...

i got the vigorgaming monsoon III for a CPU cooler, but if you go with cyberpower.... get the liquid cooling because it's wayyy better for overclocking (which the core i7 is made for)
