Best X48 mobo

[ISPEED]

i am planning on building a new gaming rig with a mobo that supports DDR3 mmemory which one of these is the best Gigabyte GA-X48T-DQ6 or ASUS Striker ii extreme the sli or crossfire does not make any difference to me as i don't see the benefit vs cost of running dual cards as to one really good one i am running a ASUS maximus formula with a E6600@3300mhz 4 gigs of ram and a evga 8800 gtx gpu. i am taking this opportunity to upgrade as my wife needs her own pc for her photography buisness lots of heavy duty graphics applications so she gets my old comp minus the 8800gtx and i get to build a new one, i guess the thread title should be X48 vs 790i.
