I recommend you download the board manual of the one you're interested in before ordering. If you can understand the language and photos, then you may have a winner. Some of these boards are written by techs whose first language isn't english. Need I say more? The abit Ip35-e was a bargain when a rebate was offered. Don't know if they still have the rebate. I wouldn't pay extra for sli or crossfire. It's easier to get a top of the line video card than 2 lesser ones. Sli and crossfire systems generate alot of heat and use alot of juice, so you usually need a $100 plus premium power supply to handle it. With a p35 chipset board, you don't need too much knowledge to overclock. I also recommend you install the memory and cpu/heatsink out of the case, on the box the board came in or a phonebook, and do a bare post, with just the cpu/heatsink, video, and one stick of memory. Then finish the install inside the case. It's easier to troubleshoot out of the case.
