I'm going to be getting a Phenom II X2 550 soon, and I'm stuck on 3 motherboards. The only real differences I see beside price and a handful of options involving USB and the like are DDR3 1800 support and north/south bridge differences. Oh, and the mobos marked as Phenom II X4 / Phenom II X3 CPU type will run a Phenom II X2, right? And just a note, I would like to try to unlock to X4. Here are the five mobos:

• GIGABYTE GA-MA770T-UD3P - cheapest 770/SB710
• ASUS M4A79XTD EVO - shiny, matches my build colors (not that I really care), DDR3 1800, 790X/SB750
• GIGABYTE GA-MA790XT-UD4P - best on-board audio, 790X/SB750

Are any of these boards stand-out, or are there any I'd want to avoid? Or are the differences not worth the prices? Which would be the best if I try my hand at overclocking?

Only certain motherboards can unlock to X4

Gigabyte GA-MA770T-UD3P

Gigabyte's 790FXT-UD5P  

790FX will be great but 770 is great bang for bucks, anyway, both of them can do the trick.

Could have sworn my research showed all those boards would work, but I'll trust whatever the forum says.

It seems all three boards are capable. I know the 3P is half as much, but I don't want to save money now, only to find that I'd have done better with one of the other boards. However, if the differences are negligible (which is what I'm really wanting confirmed, as I'm not familiar with how big the differences really are), I'll go with the 3P.
