I was looking at the xfx 9800 video card. Out from the memory it has ddr3. Do I have to run DDR3 on my motherboard before the card will work? I was getting the 780i, so can I put the ddr3 on the 780i motherboard? Also, can I run 8megs of DDR2 on the 780i with the xfx9800 video card in tri-sli?
The video card RAM (which is actually GDDR3) is in no way related to the system RAM. 790i uses DDR3, 780i doesn't. It's not worth the extra money.
