im just postin up some info i recently discovered.i dont know if anyone is aware of this but the new windows vista software only run up to 320mb for graphics card. if you try to put in a 512mb card, only 320mb of that card will we used, the rest is scrapped. i learnd this from a techie i called. im wonder why vist only allow320mb while the xp allow 512mb. luckily i been eyein the 320mb 8800 series, so i wont be over buying anything. the important thing is the 320bit interface part i guess. can anyone tell me how big of a difference runnin this card compared to a normal stock video card when playing a dvd.
