Hi. I have an iMac 2011 i5 2.7ghz with a 512mb 6770m. I also have x2 23" Cinema Displays on articulated arms. I've been trying to run Eyefinity on this setup and while it will run very few games get decent framerates as the 6770m with 512mb isn't really suited for it. I'm mainly trying to run simulators (DCS Black Shark 2, A10c Warthog, Flaming Cliffs 3 and things like iRacing and hopefully the new Assetto Corsa later this year). I've been trying to get my hands on a second hand iMac 2011 with a 2gb 6970m but they are seriously hard to come buy at a reasonable price but I can find several i5 3.1ghz models with 1gb 6970m GPU's. I've heard many say on these forums you 'need' 2gb for an eyefinity setup. Does anyone have any experience (preferably with fps benchmarks if you have any) of the 2011 1gb 6970m in this configuration. Due to the Cinema Displays limited resolution options I have to run at the following 2 resolutions. 5760x1200 5040x1050 Will the 1gb 6970m in Eyefinity show major improvements over the 512mb 6770m and if so anyone tried it. Cheers.
