I currently have a GTX 570 1280MB and would like to run a triple monitor setup. I'm building a PC for my brother for Christmas and I'm thinking about dropping my GTX 570 in his build and getting a Radeon 6970 2GB for myself. Would a single Radeon HD 6970 2GB run Battlefield 3 in Eyefinity on Medium to High Settings? The Monitors would be 1920 x1080 resolution X3.
My current rig is:
I5 2500k OC'd 4.5GHz
AsRock Extreme 3 Gen 3
EVGA GTX 570 1280MB
Corsair 750watt PSU
8GB Ripjaws RAM
1TB Samsung Spinpoint
For 3 monitors support with GTX 570, you'll have to get another one and run them in SLI to support 3 Monitors.
A single HD 6970 is capable or driving up to 4 monitors. For the best performance you can get @ high settings using Eyefinity, you have to CF the HD 6970.
but yes you'll be able to play at medium to high settings with some settings turned down like MSAA/AA.
Single GTX 570 is doing much better than the HD 6970 specially in BF3, but the CF scaling of HD 6K series is better than the GTX 5K series so 2 HD 6970s in CF will perform better than 2 GTX 570s in SLI.
