since i am an owner of the P67 Sabertooth, i'd vote - anything but that board. have had this thing 10 days and still unable to get it stable with any OC of more than .1ghz until just now (more on that below)
if you haven't made your memory choice yet, make SURE you check ASUS' QVL .pdf's. (google - mobo QVL pdf) for compatible RAM.
also worth noting is that i bought this board to build my SandyBridge PC ASAP once the Rev3 boards hit the market and the capacitors were a huge selling point. in hindsight, i wish i'd have waited for a broader selection of boards. while the MoBo cover is nice looking, it complicates the P67's terrible design choice of placing the battery under the GPU. other boards allow you to remove the GFX card to reset the battery, this one requires you to disassemble to entire rig to reset the battery.
another issue i have noticed is that the other ASUS P67 boards seem to have an OS Overclocking utility. this one has some voltage tweaks but you cannot change the CPU clock outside of the UEFI Bios. most will suggest that's not a huge deal but take it from me, after 10 Windows installs and 100's of reboots, lacking that *ability stings.
although i haven't returned mine yet, Kingston 16gb (2x4gb x2) doesn't play well with this board. despite being compatible on Kingston's website and in reviews, on the latest MoBo revision (1305) it's XMP mode is completely unstable for more than 5 mins in any test @ 1600mhz. only now have i gotten through more than 3 of IntelBurnTest maximum by lowering it to 1333mhz. hopefully this test will finish this time as its been a horrible test of patience. (test running at 4400mhz, 1.32v, 55c temp - DDR1333 9-9-9-27). Prime95? forget it - that thing killed the PC in under a minute every time.
