Hi All, They are trying to force the people just to buy VISTA, we so windows 2000 with DX8 but we can install DX9 to play DX9 games , so why No DX10 can be installed on WINDOWS XP, i think Microsoft want to push their new windows and force the people to buy new hardware or new PC. still NO DX10 games worth to waste your money on buying hardware + Vista :( . Also the people who bought 8800 GTX or GTS , most of them are happy with the performance of those cards not just DX10 , i have tried GTX & GTS 320 both cards are great in gaming.
