SO I got my 8800GTS 512mb on christmas it is the MSi OC version with 730mhz core and 1944mhz mem speeds, it is on hell of a card and I'm very pleased with it. I am playing Crysis in DX10 very high settings at 1440x900 and it is very smooth never goes below 20fps. the card came with Dirt and Lord of the rings online which I will give to my mum as I give her my old 7900GS.
I have also got my best 3Dmark06 score 13661 with my CPU at 3.6Ghz and the card at 830Mhz and 2Ghz Mem.
