I currently own a GTX 660. I was gonna buy a cheap used for for $125 for SLI. But I came across this used Powercolor Radeon 7970 (AX7970 3GBD5-M2DHV2) 3GB 384-Bit GDDR5 reference card for only $135. The seller has multiple. They were used for mining coins. I dont know much about Radeons but I hear this card is about equivalent to a GTX 680. I'm not trying to spend a lot of money so that is a big factor in my decision.
I know GTX 660 SLI outperforms a single Radeon 7970 in almost every category. If a 7970 just as strong as a GTX 680 would it make more sense to sell my GTX 660 and buy (2) of these 7970 put them Crossfire mode? The seller said they were tested in 2D and 3D games and said they were fine.
I know about SLI support in games, what about Crossfire? Do crossfire have good support in games newer and older? What does a reference card mean?
Again I dont want to spend a lot of money and I want better performance now so I dont want to get a single better card. I will be gaming on a 1080p Monitor.
