So, I recently sold my 7970 and I'm looking to get something new. I run 3x 1920x1200 Dell U2412M's. I'm not biased towards either side, I've always flip flopped between whoever has the fastest cards for the money. As far as budget goes, I'm looking at a single card, with the intent to add a 2nd soon. Right now I'm trying to decide between going 780 Classified or a 290 that can unlock. There seem to be pros and cons on both sides of the fence. The biggest for me right now is that for multi-monitor the 290's would be great, but the mining tax sort of kills the performance for money. Opinions?
