Well sata 6gbs are what future hard drives are going to be standard, unless you count hard drives are peripherals. Same thing with USB 3.0, everything is going to be it, eventually. So why not go with the curve early?
Well the one Fat Clown linked is probably the best, regardless of the usb3.0. It only has two slots for that anyways, along with 8 2.0s. Could find something cheaper, but not from gigabyte or asus AND be good quality.
It's a little older, doesn't have sata 6 or usb 3 (not major for me). Reviews are positive and seems like a good overclocker. Pretty positive so far with good benchmarking for the 750.
I would grab the p55a, even though i agree and usb3/sata3 wont be needed until well after you'll need a new build its not open box and the only real difference is that the R has esata and another regular pci slot.
Ok, so I'm gonna skip on the open box idea for an extra $10 or $20 and buy new...Thanks for the advice, sometimes I can't see the forest from the trees.
I think you should take slay's advice and fork out a little more for the mobo, remember, if the gigabyte board is faulty you'll probably end up buying another one anyway, thus spending more than you ever wanted to
