I currently have two Radeon HD 6950s and someone is offering me $350 to take them off my hands. What I was wondering is whether or not this is a good deal for me and if I should go through with it and buy another card or if I should just stick with the two 6950s. I play a few games that make use of crossfire, and I'm happy with it, but I heard that a single card is better than double cards. I have no problem with the heat and the noise is dealable. Power usage is alright too, although I wouldn't mind it being a bit lower. What do you all recommend I do? Also, if you recommend I sell and upgrade, could you recommend another GPU in its place? Preferably under $400. Thank you!
