I just had to make a new thread about this. Just got my new pc home tonight and its freaking fast. Like 10x faster than my old one.
Not to mention that I'm pretty proud that I built this myself with no experience whatsoever, but my brother-in-law did the software setup for me.
A list of what I got now
Seasonic power supply 500w
Saphire Radeon HD video card 575MHZ 512MB
Intel Core 2 Quad Q8200 processor
Asus P5Q pro mother board
OCZ Gold XTC PC2-6400 4GB
Hitachi Deskstar 500 GB hard drive
a little over $1000 with tax with the LG DVD writer, Antec 300 tower case and XP pro OS. Very happy with it!
