Of course, you would have to buy your own SLI bridge, but since you aren't interested in SLI at this time, no worries. But this board will allow you to expand in the future if you so desire.
Actaly to mod it you have to have the DFI Lanparty Ultra-D to do the mod. Just get the ultra-d and you will be happy. YES it does have 2 slots but it is not defaulted SLI, you can mod it later on down the road though.
I have been told ASUS boards were only crap when they used the VIA chipset. I was also called a f#$%n tard for even suggesting ASUS are buggy with AMD.
