I used to run G2 with a Celeron 600. It actually runs pretty well. XP will make it run a little slower, but you should be ok with a half-decent video card. I was actually getting smooth performance with a 600MHz CPU and integrated video. [X(] Can you run a GeForce FX 5200? I love mine, never had any problems. I think it was around $90, fairly cheap, yet still powerful. The 256MB RAM in the card helps a lot with XP because it's such a memory hog. Good luck, Andrew
