I just have some qestions about everything,but im wonder which way to go, crossfire or SLI for the new gaming PC i plan to biuld. i want to, at some point, dual up on graphics cards and need to make a desion right off the bat. just curious if any one out there has some personal experience, or any helpful information on the topic. i know its a loaded question because underneath it is the desision between ATI or NVIDIA. but for the most part im wondering which appears to be more compatible, if that make any sense. The CPU i want is the Atholon 64 X2 4400+. ive read some many reviews about CPU, Mobo's, and everything to the point where my whole project has been put into question. ive made several complete shopping carts full of goodies, and canceled the checkout do to indecsion. If you have any helpfull tips, please pass them my way.
