Best GPU for around $200?
I currently have two 5770s in Crossfire, and at least one of them is flaking out on me. Here's some artifact porn from Civ V, and another of Chrome starting to Zalgo. I might be able to get away with using just one of them if I determine only one is dying, but at 1440p that's kind of pushing it.
I've looked around a little bit, and it looks like an R9 280 might be the best buy. Does that seem about right? Any particular models or alternatives to suggest?
Relevant system specs: i5 2500K @ 3.6Ghz, Z68 mobo, 24gb RAM, 600W PSU, 2560x1440 monitor.
PS: I could never get Crossfire in Civ V to work in Windows 7, but it worked out of the box in Windows 8, which I installed last week. And now my glitch rate is increasing. Such sad.
