GTX 460 SLI Compatability

[radiowars]

Hey guys,
I own an MSI GTX 460 Cyclone 1GB, which I'm pretty sure is part of the original 460 series (not SE or V2) and wanted to add an additional 460 for SLI. My first choice is this:

My only worry is that mine is 256 bit whereas the eVGA is 192.

Would this GPU work in SLI with mine? If not, is there another option I can look at, considering most retailers have removed most of the 460's from stock?
Thanks,
RW

edit: I've never actually understood the differences in the GTX 460 versions, so that's why I'm asking for help choosing a partner GPU. Not because I'm lazy

It likely won't work due to the memory interface difference.
