check this out, you might find it interesting and consider DFI...

sorry for the double post..

Ultra-D vs. Fatal1ty AN8:

Both motherboards are great overclockers and both are built with gaming in mind.  So which is the better board?  Straight from the facts, we can see that the Ultra-D is a better board.  But if you put consider all aspects of a motherboard, it can be a tough choice.  The DFI Ultra-D is honestly the best overclocking motherboard available.  The voltage options are great and the frequency ceiling seems too high to reach.  The bad part about the board is that the layout plainly sucks.  It causes compatibility issues as well as cooling issues.  The Abit Fatal1ty AN8 also provides great overclocking headroom, but not as great as the Ultra-D.  The lack of VDIMM makes memory choice limited to using TCCD chips.  Users looking to use the new BH5 for low latencies will be quite disappointed.  You can go out and get the OCZ DDR Booster to increase your VDIMM options, but you'll be drawing power from the 3.3v rail and probably be limited to 3.4v.  In order to get some good voltages, you'll need to do a power supply mod to stabilize that 3.3v rail.  The Fatal1ty AN8 does provide better motherboard layout.  While this in no way affects performance, it does allow better arrangement of cables and better cooling.  Users can use waterblocks for their Northbridge or large heatsinks for both the graphic card and the CPU.  As for cooling, while no tests are conducted, the Fatal1ty AN8 does run cooler.  With the DFI Ultra-D under load, I can feel heat emanating from the motherboard.  The Fatal1ty AN8 didn't have this strange heat wave.  In terms of looks, I personally like the Fatal1ty AN8.  The fiery red PCB and red motherboard LED's looks great in windowed cases.

I guess it really comes down to the user's preference.  If you want pure power, you can't go wrong with the Ultra-D.  It is a bottleneck-free motherboard aimed to get the most of all your components.  If you want both performance AND looks, the Fatal1ty AN8 is the better route.  I'm sure that the majority of enthusiasts will go for the Ultra-D because of the great overclocking potential.  As a gamer who owns both boards, the Fatal1ty AN8 goes in my gaming rig while the Ultra-D goes in my test bench.  I'm the type who likes to frag with style.  Since I don't have the fragging skills, I'll have an pretty overclocked box to back me up.

common sense... ABIT comes with low vDimm, so you're limited with those super expensive TCCDs... on the DFI side... you get 4.0vDimm where u can have multiple choice on rams... my best bet would be UTTs as they're cheaper than TCCDs, and they do massive clockspeeds with super tight timings... tighter than the TCCDs... here's the biggest point to point out here among those boards

Ultra D can SLI also..but you need the PCIe bridge...

DFI fan please beat this....
