Its a noticeable upgrade! Went from 2560x1440 with a mix of med/high to all high + FXAA at the same or slightly higher FPS. Thats at 1100/1650 core/mem mhz. HardOCP's review had their card up to 1280/~1800 core/mem with voltage tweaking so I'm sure I can wring a pretty healthy boost of performance out still. it runs several deg cooler than my 460's (65C vs 75C) while being significantly quieter at the same time. I'm also sure power consumption is down substantially as well. On top of that I can now have all 3monitors (1440P main w/ 2x1080P accessories) lit while maintaining full gaming performance.
I'm sure that the 680 would be capable of delivering all this as well, but for at least $50 more and whenever the hell Amazon feels like getting it in stock.. so I don't think this was a mistake![]()
