I cant read the comments of this topic for some reason, there for i remove it
the 7970 is a more powerfull card so if your using multiple monitors then you would get better fps but not by alot i dont think.but then again the 7950 is 100 euros cheaper
It is kinda hard to deside, but it seems no one tested them against eachother in eyefinity yet. But since im planning on building a new rig next year. I think the 7950 will be cheap and nice for now.
Please egnore the comments above, that was of when i wasnt sure to get a 7970 or a 7850.
