i have got an e8200 running on xfx 680i motherboard . i want to add 8800GT from XFX to my rig . as we all know , the card is pci express 2.0 while the board is not . so can i get the card running on my motherboard ? i googled and found out that it should work but i do not want to take any chances as i won't be able to buy a new motherboard right now if this does not work.
