Right now the best consumer motherboard is the Skulltrail from Intel.
It's loving expensive on it's own, but couple that cost with the cost of the 2 processor's it requires to run ($1500 each) that thing is amazingly expensive. I mean, it can run on just one processor...but why buy that board then?
Intel is leading the way with CPUs and buying an AMD processor doesn't make much sense now unless you are aiming for a really, really cheap computer.
There are Intel boards that support AMD processors.
AMD/ATI are kicking Nvidia's ass right now with GPUs though. The competition is really helping lower prices.
