With the new AM2+'s coming out I just have one question: Will I be able to use Nvidia graphics cards on these boards, more importantly SLI them? All I'm seeing is "crossfire supported" which is Radeon based. If I get this board for example
SLI is an nVidia owned/copywrited technology: So for 'official' support you will have to wait for nVidia to either create a chipset that supports your choice of processor, or licence the technology to someone who will.
If you don't want to use hacked drivers off of the Internet - which may or may not exist, may or may not work well or even at all, and definitely won't have even the garbage that passes for "support" at most companies - then you will have to use ATI/Crossfire or a single nVidia card.
I think you'll be able to use four ATI 3870 cards, wow!!! If you use nVidia cards you won't be able to use SLI, but you can have up to 8 monitors, two for each card. Now if only they had a CPU that can keep up with this...
