Best EVGA X58 Overall for OC

I have a pre-built system that I want to upgrade with components that will eventually be moved into an Ivy Bridge (or the current intel offering) sometime next year. Here are my current specs:

HP 580t-Elite
i7 950 Quad Core 3.07 GHz
9GB Ram
Pegatron 2a86 Mobo (HAHA)
Radeon HD 6450 (LOLOL)
Stock PSU 450W (ROFLOLOL)

Being so close to Ivy Bridge I thought it would be prudent to stick with my current processor and make high end upgrades that could be moved over once everything has been released. Upgrades planned:

Corsair Vengeance 16GB RAM
EVGA GTX 580 (HURRY UP 600 SERIES ) or AMD 7970 -- Still undecided
Corsair H100 CPU Cooler
Corsair HX 850W
Corsair 650D Case

What X58 Mobo do you recommend from the EVGA line? I am looking for a board that is easy to OC and stable. I will also be adding a second GPU down the line so it will need to be Xfire and SLI compatible. I have a nice EVGA discount which makes the entire line a good choice price wise. Anyone with experience with these boards -- I need your advice!

i wouldnt bother moving to ivy bridge with an i7 950...
for gfx cards i would go for a 6950 or 6850 for crossfire... they cheap since the new line is out ...

evga only has 3 x58 boards listed on their site, this is the cheapest one here... http://www.evga.com/products/moreI [...] amily&sw=5
