Rampage or rampage extreme...or something else

I have $370 dollars to spend but i am not looking to upgrade to the i7's yet, so i am going for the next best thing.

Setup now
asus 750i (POS edition)
2gig of ddr2 800mhz
gtx 260

What should i upgrade?
I hate my motherboard so i am definitely looking for an upgrade in that department.

I was thinking either of these

Rampage Forumla


Rampage extreme

I save a Lil bit more on the Forumla so i can upgrade my ram, with out the price of ddr3

Or is there any other suggestions?
