best nf4 ultra board out,its an all around board meaning it does everything well.not just o/clock.asus a8n-e.had 3 other ultra boards before this one and there is no comparison.its my feeling this board is as close to being a perfect board as can be .the layout is perfect,bios is mature and troble free.not picky with hardware like dfi boards.dosent run hot like the heatpipe cooling boards.you can put a wide range of aftermarket coolers on the nf4 chipset and dosent interfear with large video cards.has decent sound onboard.all in all a very stable ,very stable board.to me sli is a waste of money,with 1 late top of the line video card game performance is pretty close to the sli version.if you have to have sli the asus a8n sli is the sister board to this one.all things apply to this board as apply to the a8n-e board.you cant beat these asus nf4 boards.very affordable too.93.00 for the a8ne and 104.00 for the a8n sli.check it out and you wont be dissapointed,i garrantee dude.
