Basically, a few years ago I bought a pretty nice desktop from someone who was really into high-end hardware. He had a SLI set up with a 2 gb GTX 460 as a primary card, and a 512 mb 9800 GTX as a PHYS X card.
What I'm looking at getting is a 2 gb GTX 770 Windforce 3x card. http://www.newegg.com/Product/Product.aspx?Item=N82E16814125463
My first question is if it is possible to run the GTX 770 as the primary card, and the GTX 460 as a PHYS X card. Again, I'm an idiot when it comes to this, but using the PHYS X set up, the 770 won't be bottlenecked by the 460, correct? I've heard with SLI that the better card can be held back by the lesser card, but the set up in my desktop as is seems to indicate otherwise. If I can't run these cards together effectively, will the 770 on its own be significantly better than the 460/9800 combo I'm running now?
Finally, I've heard that the 770 has the option for a 6 pin or 8 pin connection to the power supply. Reviews I had read on the card said pretty much across the board that the 6 pin is not recommended. My current cards look like they have 6 pin connections to the PSU so my assumption is that that's what I have to use. Is it a huge issue if that's how I need it to be connected?
Sorry if any of that seemed confusing. It's a bit difficult to describe stuff that you yourself don't understand in full haha. Please advise!
