I currently run a 570 and have been pleased with it's performance though I have always wanted to run my games (Skyrim and BF3) on higher settings.
I've pretty well decided on the 680 SC but have a few questions I can't find answers to.
First, if I run the new 680, is there any reason not to sell the 570?
Could it be of any use as a PhysX card?
Second, since I have a PCIe x1 USB 3.0 internal controller card for the USB header, would that force the lanes for dual graphics cards into a x16/x8 configuration?
The MB has a NF200 controller but not sure if that gives any benefit.
In my digging around, I found what seemed like a good thread that started to answer this question, then proved to be as entertaining as it was informative. http://www.overclock.net/...ut-p67-z68-pci-e-lanes
My knowledge of SLI and it's options is limited and I would greatly appreciate some advice.
Unrelated question: Better to run a DVI to the TV, and a seperate audio (optical) cable from the MB to my receiver than an HDMI cable from the graphics card to the TV?
