Is this ranking a good indication of GPU and gaming performance?
The 9800GTX/GTX+/GTS250 and 4850 serves as the base value of 1.0 - with higher values being better performance. This is with SLi/Xfire enabled games. This is a general indicator of performance - not specifically fps benchmarks, since Xfire/SLi fps improvements can vary widely in different games.
(ie. Crysis gets maybe a 30-40% fps boost while COD4 gets maybe a 70-80% fps boost)
