OT: Building a new computer...

[Raapys]

Quad Cores aren't completely useless. You will get a faster computer overall. However, few applications yet take advantage of all the cores. Photoshop and 3DStudioMax are programs that benefit enormously from quad core( or even more cores ). Upcoming games like Crysis, and all games being made with the UnrealEngine3.0( that's alot of games ), are designed to take advantage of 2 or more cores. The future is Quad Core, really. But with brand new Intel and AMD quad cores coming up within the next few months, there's little use buying the current quad cores on the market.

Especially interesting is the AMD quad core, since they've been sort of 'out of the loop' lately it will be interesting to see how theirs perform compared to Intel's.
