I honestly don't know if this is a good card or not as I'm not a Radeon fan but... http://www.woot.com/ -KM
Yeah, it's a little on the underpowered scale. Better than mine though, and I can still compete for a 3 year old card (I have an x1600)
If you look hard enough 8800gt's can be found for 100ish. I'm sure ati 3870 and 3850s are being sold around that price from time to time as well.
