whats not to like? i strongly believe this is the best mobo on the market, handles my cpu wonderfully, can put 3 gpu's that take up two slots each on this mobo! reapplied thermal compound to the heatsinks on the north and south bridge but i didnt have to, just a little overkill on my part... asus update makes bios updates convenient and plenty of drivers and extra programs come with it!

rig:
amd phenom II x4 955 oced 3.71 ghz
cooled by coolermaster v8
sapphire ati radeon hd 4870 oced core clock 820 mem clock 1030
4 gb ocz amd edition ddr3 1600 mhz
corsair 750w psu
wd 640 gb black
oh and antec 1200 (another highly recommended item by me, so roomy and great air flow)

AMD made the mold for overclocking processors with the original "Thunderbirds", and these are the legacy in Quad form. While they may not air cool to 4+GHz like the Intel comparison of the 975 Quad, they do their jobs without the 5x pricetag. They will clock with stock air cool to 3.65GHz, and aftermarket cooler to 3.9GHz easily. Water cool for over 4Ghz. AMD makes great processors, I can testify to that, since the late 90's. Gamez, Movies, Rips, heavy or lite jobs, these will do the trick. If you know a little about clocking your own systems or just want to learn this is a great place to start (if you mess one up, your ok cuz you still have 4 more processors to puchase before you reach the cash value of a Intel, lol).

I upgraded my MB since my MSI fan started to make noise and finally cracked !!! This is a very friendly and wonderful MB. Keep cool temperatures all the time with "normal" office and photowork - no games - Works great with my AMD 64x2 5200 processor. Recommended product.
