Gtx 660 Ti SLI question

I was wondering if i could run two different Gtx 660 Ti cards in SLI, like the MSI version of the card and the EVGA version.

Yes as long as the memory size matches.

Thank you for your answer, this was more of a question for thought instead of a serious one, if i was going to run it in sli i would just get another MSI 660 Ti, for uniformity of course.

That is what I did with my 670's I bought both from EVGA just because I like the company and the warranties.  The conformity factor had a small role in it also.
