Depending on the specs.. SLI or crossfire.
THe UD3P gigabyte will be your best bet, or the P5Q PRO ASUS. for Crossfire,
you'll need a little more for SLI. Just to do SLI you will need to have atleast $185.00 before m-i-r on the evga 750i, and on the ASUS sli's are over $200 mobo's.
so think twice on SLI..
well, there is one that i found, but it hasn't had much of a good review yet to be seen..http://www.newegg.com/Product/Product.aspx?Item=N82E16813131232
$134.99 so + shipping looking at around $145.00
