They're both awful, but I think the 8200 is better.
nvidia 8200 gpu score 4.7 ati 3100 is a 3.6
nvidia geforce 8200 is a motherboard, not a sound card. It has a Realtek HDA (Azalia) soundcard integrated.
Well, I highly doubt it will, plus it depends on how fast your CPU is. I'd prefer the nvidia 9800 which will run left 4 dead on high and lets say you SHOULD have a 2.2 Ghz CPU or better. I hope this was most helpful for you. i really suggest you ignore the guy above me i can run left 4 dead on a sempron le-1200 824mb ram (1gig basically) and a Geforce 6100, on LOW the 8200 can run it at medium/high settings im ordering the XFX mobo for that 8200 because im almost positive it will work for ya
20% of 8200= 20% * 8200= 0.2 * 8200= 1,640
