I actually have both and the MSI card all by it self run super nice but I am running sli and those cards won't play nice in sli IMO. I have to put the MSI card on the bottom so it can get some air. I think that even if you had 2 MSI cards the top one would suffacate. My MSI card runs 48c idle and 65 under load in my sli. While the EVGA runs 46c idle and 78-80 under load with the EVGA being the top card. If that helps at all?
Thanks. Do you recommend two twin frozr cards or two superclocked+ cards in sli? This is in a case with good air flow of course.
