For one, Conroe will be better at games than the current AMD processors. That's a no-brainer. Also, all 7800GT's are legacy models and are priced at about 300 bucks, whilst the 7900GT's are priced lower, in the upper 200's. Grab a non-overclocked (from the factory) 7900GT... The stock overclocked ones are supposed to be very unstable.
