My vote is for ASUS P6T. I picked a new one up for 175$ with cashback, but id probably pay in the low 200$s for it. Its a great board, has all the overclocking tools you could possibly need and then some. Its also has a nice layout out as well. If your looking to do tri-fire or did you mean cross fire? This board has 2 16x PCIE slots and CAN do tri-fire but the other PCIE is only 4x. If you did mean tri-fire your board will probably cost you in the 250+ range.
