I don't think he meant to say that you couldn't run surround with 2 580 cards. I'm proof you can. 2 570's should be able to run surround, just go for the higher VRAM versions. Surround is fantastic, you will love it. It's hard to even use a single monitor after using surround.
Sadly I've only got $550 so 570s are out of my budget
Now THAT sounds temptating... they're supposed to go out January 9 right? Benchies should be out soon... but hows going to be availability?
I need to choose soon because someone is going to buy my 560 for a really good price but limited time offer.
Thank you everyone for your answers! +Rep
