I voted P5B DLX but the DS3 is also good.....just that I don't know my way around with GIGABYTE boards.
See, back in the days of Socket 478, ASUS and ABIT were at each other's throat but then ABIT almost went bankrupt and Pretty much the first Socket 775 board (s) were ASUS that put the stamp on them being the #1 choice for overclockers, then, the same thing for 955X and 975X.
But for some odd reason, GIGABYTE took ABIT's place in challenging ASUS at what they're the best and the DS3 is a pretty good challenging board for any ASUS right now.
And like I said, I don't know my way around the BIOS on the GIGABYTE, so I'll have to say the P5B DLX is the best.......
Ropey may have a different opinion, since that he's got the DS3.
But if any, this could help: http://www.pcper.com/article.php?aid...e=expert&pid=7
Performance wise? They're the same, but over-clocking points? I only know the ASUS.
