I know that its not a real competition, but just how much of a difference IS there in the real world between BFG 9800 GT 512 MB and HIS Radeon 5750 1GB? As of today, the 9800GT can churn out fantastic graphics at very acceptable frame rates in just about any game from NFS Shift to Fallout 3 under maxed out settings (Except Anti Aliasing) with the resolution of 1920 x 1200. Is an upgrade really worth it?
