Best mobo for XP-M?

Hi, i've been messing around with overclocking for quite some time now on my XP 2700+ that i've recently sold. So i'm looking for a new OC project and i've stumbled upon the AMD XP-M 2600+ and that shall be my processor of choice, and i've picked out all the components of the setup except the motherboard, i've read some reviews on OCing the XP-M but each one had a different mobo so i'm having a hard time selecting the best one. Someone please guide me to the best mobo for my app .

Setup:
Acrylic Case
Cooler Master 450W w/active PFC PSU
Athlon XP-M 2600+
Geil Ultra 2x512 DDR PC4400
Raptor 36GB SATA
X850XT Platinum Edition
Still choosing the watercooling unit

The most popular board is going to be the Abit NF7-S. There are a handfull of other good ones, but the NF7-S is a proven board with lots of support and modded Bios's.
