I'm not that bright when it comes to hardware. When I attempt to install it, I may be installing it incorrectly, but the wiring seems troubling and is giving me issues of plugging both into the correct places.
I already bought the 570 GTX from Newegg and it's pass the 30 day limit to return it for the full price I bought it for. For video games, if I were to buy the GTX 660, how much of a difference would the 570 be in comparison to the 660 when speaking in terms of FPS?
Well I'd love to help you but I can't figure out what the issue is. The 660Ti would be an improvement, but not really worth it. You would see a performance increase but not enough to justify the more money you spend on it.
Do you have a cell phone with a camera? You could take a picture with it.
Anyway, on the GTX 570 should two power sockets. One 6-pin and another 8-pin one. Your power supply will have those for just, but don't confuse which 8-pin to use: it will say PCIe on it. There's another 8-pin connector which is used for CPU power, and it will not fit inside GTX 570 socket.
