Rate my i7 920 Build

If you're going to spend that much might as well get Liquid Cooling.
Build looks flawless, otherwise. Should be a beast.

The Mugen 2 is good cooler, but to really take an i7 to it's air cooled limits, you'll need something more.

Noctua's new NH-D14 is the best performing air cooler money can buy atm (it just nudges out the IFX-14 by a few degrees and is much easier to mount), but it costs an arm and a leg.

The Prolimatech Megalems would be my next choice.

You really don't need DDR3-2000. The performance difference between 1600 and 2000 in real world use is in the very low single digit percentages. To even run triple channel DDR3-2000 you need to run a 4Ghz+ uncore clock, and this is going to take a lot of uncore (QPI/vtt) voltage, and make a decent bit of extra heat.

Then again, most DDR3-2000 will run 1600 with tight timings and given current DDR3 prices, you may not save all that much by going with slower memory.

So, I'm really not sure on memory at this point. I think it's all a rip off (the 4GiB in my system was about 45 dollars total) as prices have jumped recently.

GPU is overkill and you should be trying to get a D0 stepping i7 920. Also, Meghalems are much better.

for the 1TB drives i get the new samsung spin point F3s. they are very good drives. and change the SSD to a OCZ Vertex or agility SSD. Other then that it looks great. Well except for the cooler get the prolimatech megahalem or Noctua NH-D14. The case is also pretty lame for that build. Why not get like a cooler gaming case or something like cooler master storm sniper or Antec twelve hundred?

why? its a true fact. when the core i7 is overclocked its beat phenom II in everything. These chips should not be compared though. the Phenom II X4 chips where meant to compete with intel Q9xxx chips.
