I've got an AMD at home. It's plenty fast enough for me. Never seen it lag in any games I've tried... I need a better vid card, and an actual sound CARD< not the internal BS, and my PC should be about all I'll need for the next 2-3 years, HOPEFULLY.
I play Warcraft III on 1600x1200x32, everything on maximum, and never had problems.
[edit] I guess I should post my system info...
About a year old now:
Lian Li PC-50 case w/ all Stock cooling system
450w brand name power supply (can't remember who
)
AMD PC2100+ 1.73 Ghz
512 MB Samsung 2600 (I think) RAM
Asus A7V8X motherboard
Visiontek GeForce 3 Ti Vid card
WD 80gb, 7200 RPM, 8mb cache HDD
Sony 48x24x28 CDRW
Sony 16x DVD-ROM (Wish I had a DVD Writer for all my MP3 backups)

Pic of my case <but mine's got ugly white drive faces... not brave enought to paint them.
