as far as i can tell, the 3rd one can unlock cores, and lacks the UNIQUE features such as
Support for @BIOS
Support for Q-Flash
Support for Xpress BIOS Rescue
Support for Download Center
Support for Xpress Install
Support for Xpress Recovery2
Support for EasyTune (Note 5)
Support for Easy Energy Saver
Support for Smart Recovery
Support for Auto Green
Support for On/Off Charge
Support for Q-Share

More about what major difference mobos confused
  1. The GA-790XTA-UD4 AM3 has SATA 6Gb/s and USB 3.0 support.
  2. i see.. looks like board #1 has more features and more futureproof for bout 10 bucks more after mir.

    whats a decent ram under 140 for that first mobo?
  3. what about this one?


    its got a lower timing(i think thats good)

    7-8-24, while im at it, can someone explains what that means?

    and why its better than 9-9-24?
  4. They'll be slightly faster because of tighter timings, but benchmarks are required to tell the difference. According to their specs: "Specifically Designed to compatible with Intel Core i5 and Core i7 for Intel P55 motherboard." It doesn't mean that they won't work with your motherboard, but unlike the kits that I suggested that work well with the AMD chipset, several people have run into issues with your suggested G.Skill kit (read the reviews on Newegg).

    If you increase the voltage of the G.Skill kit that I suggested, it might run at the same timings. Are you looking for system stability or best performance on benchmarks?
