PART I of V : Return of AMD FX, Enter Gigabyte
My System:
The first thing that came to mind when I first laid eyes on my new Gigabyte 990FX UD7 board was that it was quite the beautiful board. Much respect for the simple PCIE 16x slot latches, the Crosshair V uses a more traditional type, and sleek heatsink design.
EDIT: It should be noted that I received a revision 1.1 board from Newegg Canada, and that it does have Load Line Calibration (LLC) controls in the bios.
The new Team Xtreem DDR3 ram has a cheap but cool looking reflecting sticker, but what is most appealing are the stats: 2400 Mhz @ Cl9, which is only surpassed by Corsair's grossly overpriced and discontinued Dominator GT dual channel flagship memory.
The memory height is not found online, and could be helpful to potential buyers.
Team Xtreem memory height : 52mm
Promlatech Genesis allowed height: 54mm
So this is awfully close to the tallest ram you could use with this cooler. I have seen Dominator GT ram at a height of 54mm barley fitting underneath the heat sink, found here, and a 53 mm Corsair Vengeance stick here.

Discussion:
We see that for the benchmarks used in Part I of my review, FX only falls signficantly behind when only a single thread is used. When only one core is being used we see a 25-40% benefit per Ghz for the 3770k over the FX 8150.
When all threads can be used, Bulldozer does a good job of making up for the lost single threaded performance. Scaling for FX outshines the i7 3770k by a significant margin. Most notably with techarp's x264 HD, where my FX 8150 @ 4.9 Ghz beats a 5.0 Ghz 2600k, and narrowly loses to a 4.9 Ghz 3770k. (Check source 19)
In TrueCrypt 7.1a we see a 4.9 Ghz FX 8150 performing slightly better than its 22nm 3770k intel counterpart at 4.7 Ghz.
In 7-Zip we see the FX 8150 jumping 2.7 % percent ahead of its 3770k counterpart at the same 4.9 Ghz clock for Compression, but falling behind 2.7% with decompression.
The temperature of a 3770k is also seen to sky-rocket up to 78C during a SuperPi 32m test, while my FX 8150 doest hit above 59C.
Next week well see how my GPU handles graphically intensive workloads on my new Gigabyte board.
Stay Tuned! I am free to answer any questions and also am willing to take any requests you guys might have!
