m2n-sli deluxe what kind of CPU upgrade?

[Hefemeister]

The latest bios ver 1604 added support for the 9550.

That is as good as you will get.

Yep, just had a check myself, i don't think theres much hope for using a II in there. The 9950 will still be a great upgrade along with a 4870 anyway, They should really be cheaper then 150 though considering the prices of the 940 and 720.
