i would obviously use 2 6990's or 590's, duh, but from a actually realistic stand point, idk, just depends on how much i have, for the under 200 area, well i'd check to see if any of the cards had the deals for a free game, that i liked, then if it is reviewed well and no more than like 40 over the first card of the model worth getting (cheapest 4+ star with 30+ ratings prefered to me), but overall just for the card alone, i'd prob just go for like the gtx 560's around 200, would look for a specific card but on my comp which has slow internet.
