mixing evga and xfx 7900 gtx's for sli

[WaXmAn]

I have had my evga 7900 gtx for a week and now dell decided to send me the xfx 7900 gtx I cancelled. Can I take both brands and put them together for sli? Will they work together? Can it kill the cards? Sorry if this is a dumb question.

it should work, though if the cards are clocked differently they will downclock to the slowest card

will work
