Within the next few months I'll be building a new computer. Its my first build, so there's a few questions I have. First off, I plan on using it mostly for gaming, mainly CS:S. Here are some system specs that I threw together:
intel Pentium 4 640 Prescott 3.2GHz
ABIT Fatal1ty AA8XE or ABIT AA8XE
1GB (2x 512MB) Corsair XMS 240-pin DDR2 SDRAM
Rosewill 256MB Radeon ATi x800XL GDDR3 PCI-Express x16
2x 80GB Seagate Barracude Serial ATA150 7200 RPM
Not sure on case as of yet...any suggestions?

Okay, is the Fatal1ty price worth the performance you get? Am I making a good decision with intel over AMD, or should I look at AMD? Is that a good choice of a video card, or is the 6800GT a little better in gaming performance? If you guys could help me out, I'd greatly appreciate it.
I'm really impressed with your site and how friendly everyone on here seems to be, so keep up the good work guys! Thanks in advance!
