Here's my thinking.. I generally don't have SLI enabled as some of the stuff I run gets twitchy with it enabled, so single GPU card with a gtx260 as a phyx card (have one in my other system which will get my 2x285's for some folding fun and a back up system ).
Heat and power consumptions do not consern me, I will throw a water block on whatever ever I get.

(or maybe just the vapor-x one)
I like running full settings (1920x1200) and aa and mainly play online rpg type games, some movie watching (sometimes at the same time ).. 2nd monitor can run off the phyx card..
Any real reason to choose one over the other?
