I've never crossfired or sli'd before but I'm looking to purchase another 4850 to join my Asus 4850 512 DDR3 card. Back when I built my rig I had the possibility of crossfire in mind so my setup can support the necessary power and motherboard needs. Yet I have a few questions about the setup.
1. I'm running a E8400 at 3.0GHz (was clocked to 3.6) will this cpu bottleneck on 2x 4850's?
2. I looked on newegg and noticed a DDR5 4850 if I purchase this will it have problems in crossfire with a older 4850 running DDR3?
