@D2ultima Hi new to forum old to life, Probably a strange question but from what I could wade thru of this thread you are VERY likely to have an intelligent answer for it. A while back I replaced my two 660ti cards (in sli) with a Titan Xp (obscenely expensive and paid more than retail). the question: can those two cards be put in the system as physics only cards? SLI with each other (not w/Titan) used as kinda math co-processors? The worry is smoking a lot of gear! Have been playing around with a lot of CUDA programming and would like to have all the processors to work with at once.
