I want to upgrade my geforce 8800GS 384mb to either ati 4850 512mb or gts 250 512mb. i cant afford the 1GB version of both cards as they are way more expensive in here where i live. so which one is better? I couldnt find any review for GTS 250 512mb version. the gts 250 1gb version seems to be faster than 4850 in most bechmarks but i dont know about the 512mb version. what do u think? which card is better buy??? ati 4850 has 800 shader ps , does it mean it will cope better with future shader intensive games than gt2 250 or not?? Thanks.
