u crazy magnet? who told u that? no way . the thing is that there isn't a lot of performance difference due to the memory requirement of the game. games that utilise more graphic card memory run better with more memory having gfx cards. u can see that clearly in a shootout between the ati radeon 9800 and the nvidia 6600. u will notice that the radeon outperforms the 6600 only in memory intensive games. that too by only 2-5 pts. plus the new pixel shader 3.0 and vertex shader 3.0 wasn't added just like that. these features use memory very much.
