I am currently using a 512MB HD 3870 Toxic on a VW266H (25.5in @ 1920x1200) and a E172FP (17in @ 1280x1024). I play Civ V and a bunch of older games: NHL 09, NFSU2, RCT, etc. Well, I just got a steal on a used U2410f A03. I will be using it as my main monitor with the E172FP as my secondary and the VW266H as my third. I want to be able to play Crysis 3 on the U2410f at full resolution, but doesn't need to be highest graphics setting. I will be playing games (Civ V, NHL 09, Crysis 3 mostly), using SketchUp, Office, Skype, occasionally Photoshop and watching Blu-ray movies. I am a heavy multi-tasker; often browsing web, IM'ing on Skype, using SketchUp, and watching a movie or listening to FLAC. Which GPU should I upgrade to? I would like to connect U2410f to either DVI or DP, the VW266H to HDMI. the E172FP only has VGA, so I assume I'll need an adapter for that; using DVI-to-VGA adapter currently. Would it be possible to Crossfire a new AMD GPU with my HD 3870? Would it even be worth it to? update. ordered the PowerColor HD 7950 3GB.
