Ight im building a computer so far so good. The only little problem i see is that my mother board says it needs DDR2 800 so im buying to gigs of gskill DDR2 800 yet when i look at the memory requirements for the good videcards cough geforce 8 series it says it requires GDDR3. What the h3ll does the G mean and does this mean DDR3 or does it mean you have to overclock your DDR2 ram. Keep in mine I am nubcakes so please answer you can laugh a little on the inside ;-P!
