No. 2 video cards do not work with CS6. On a Z77 platform and with CC it is a waste of money. You will reduce the speed of your primary video card from x16 to x8, resulting in around 10 - 15% performance degradation. Forget it.
Thanks John for the threads and placing me in the right area.
@CC merchant, thanks for the heads up on the card. Some great things about adobe and some not. I guess I will use my old dell and gut it for the case and fan and run twin 700gtx's with an cheap I5 and 16gb of RAM and make a Render farm out of it for My 3D Blender work then.
I had a buddy refer me to the 700 series which seems like a deal and since Blender from day 1 took render into consideration when creating is why I wondered if Adobe was going to be the bottle neck here.
From what I see I do not think it is the Z77 platform that is the bottleneck with option of 3 GPU's rather Adobe's not accessing two cards in SLI or NOT and also needing the EXACT same drivers to Jibe...
Appreciate the input and feedback. I wish there were some references though. All was 5.5 from those links and what you stated....
Thanks CC will do thanks for the link to Tweekers Page
