    Hi guys,

    I originally posted this over on the Mac Games section but have not received a reply. Thought maybe posting here would be better.

    I'm starting a research project that will use both a 23" ACD and the Oculus Rift (OR). Half the sample (people) will use the 23" ACD and the other half will use the OR. The computer I'm using is a 2008 MP with 16GB of memory and a flashed GTX 570 with 2.5 GB of memory. I'm using Unreal Engine 4.x to create the app. Right now, the best frame rate I can get hovers between 23 and 26 fps. To my eye and given the nature of the app, I can live with that. However, the frame rate drops quite often to <20 fps. That I can't live with. iStat Pro is showing very little use of the CPUs and I have plenty of system memory in reserve and/or idle.

    So, given the above info, can anyone recommend a GPU that can up my frame rate to a consistent 30 fps in a graphics intense application without breaking the bank? As with my GTX 570, I'd probably buy the card from MacVidCards.

    Thanks Lou! I think I'll load 10.8.5 just for development of this app and see if it runs better.
