Need a block for 775

Whats the best block that I can pick up for my 660 lga 775?

Thx for help

The best current block that's easily available (hopefully) is the new Swiftech version of the Storm G4. Swiftech has them on their site, but I really don't know how "available" they are; if they actually have them in stock, that's the way to go.

thx just pre-ordered one.
