debating a second gtx 590 or two gtx 580 3gb's
I already have a evga gtx 590. I was considering gettting another for quad sli but I am not sure if the 990fx will support quad sli even though it's still 2 way technically. If not, I was thinking of giving my brother the gtx 590 and buying two gtx 580 3gb's. If that's the path I should take in the gtx 580's, I wouldn't mind getting the msi lightning extreme 3gb if I did since I could go for sure two way sli in that sense without wonder or worry that I would be stuck with a second gtx 590 that I can't use. any thoughts?
