GA-P55-US3L 1.0 vs 2.3

We mere mortals are not permitted to know the differences between revs...


...depends mainly upon your intended use for the system!

The revisions "fixes", "sometimes added "features" and typically hardware related so the latest revision the better. Best MOBO for your CPU and in the same price range

Asus P7P55D-E Pro ($180 US)
GA-P55A-UD3 ($140 US)
EVGA P55 TR ($90 US)

Good Luck!

Use it for programming, office and gaming. So, average user, not design/rendering stuff (only a little, just for fun). I'll cope it with 4gb and GTS250 1gb graphics card, just to pump up the gaming department  

I think you'll be happy with it. The only real difference between the older 55's, and the newer 55A's is the USB3 and SATA3 ports, and, in my opinion, USB of any sort is a poor choice for external drives, and the SATA3 ports are entirely useless - just a marketing ploy... I've been recommending the H55's and Clarkdales for less expensive systems - the graphics are great for 2D, and much cheaper than a seperate vidcard, but you really wouldn't want to game with 'em!

I'd still recommend the same MOBO's, I assumed everyday + gaming {CF + SLI support} and all of the necessities for everyday and tomorrow:

You happen to be in BA? Some years back, did a Pepsi plant across the bay in Colonia in Uruguay - used to take the hydrofoil accros the bay to BA on weekends to party - women were prettier than in Montevideo!
