My current computer (my parents computer):
Intel celeron D
256mb RAM
Onboard Video and Sound
.... You get the idea. It's a piece of crap.
The computer I'm getting ready to build:
Intel Core 2 Quad 2.4GHz
4GB DDR2 800
Nvidea GeForce 8800GT 512mb
150GB Raptor HDD
....
I'll eventually upgrade to 8GB RAM, and another Raptor HDD (and two monitors).
