Which RAM of these is the best choice

Hello everyone
I am completing my first C2D setup and now only RAM left to choose (2xGB DDR2), The rest of the company is Asus P5B-E Plus and E4300. I want to OC to level usable in typical daily usage.
My budget and local availability narrowed choices to:
GEIL Ultra CL4 /800
GEIL Ultra CL3 /667
OCZ Platinum CL4 /800
OCZ Platinum Rev2 CL4/800
OCZ Special Ops CL5/800
Corsair XMS Twin2X CL5/800

Or maybe some of these cheaper ones will OC to similar levels

GEIL non-Ultra CL4/667
Patriot Signature CL5 /667
OCZ System Elite CL5/667

So, what do you think?

I have a buddy with this G. Skill RAM (see link). It's probably the best bang for the buck for CAS 4 DDR2-800 RAM. It's currently out of stock at newegg, but is due to be back in stock early next week.

I am limited to just these above , because I live in Poland and I want to have local warranty.

I read a lot of good decent reviews on the OCZ platinum rev 2. It dosnt overclock as high as the more expensive ram, but its right there with any of the affordable choices. I like the fact they allow you to over volt the ram (within reason) and still maintain your warranty.

i have G skills and i love them. but whatever floats your boat. timing is different on all of those probably.
