i bought a prebuilt HP machine about a year ago, the hp pavilion elite m9250f. i upgraded the memory to 8gigs, added a new psu, and put in a new video card a month after i got the machine, so i am now thinking about getting a new video card. the mobo is the intell g33, it says its PCI Express x16 and PCI Express x1. i dont know much about the new video cards and the compatibility issues. i was thinking about getting the gtx 460 card. but that says its a PCI Express 2.0 x16, does that mean im out of luck in getting a new card?
