I am building a new PC, but I can't choose between the MSI N680 Lightning and the eVGA GTX 680 SC+ (notice the +). Benchmarks indicate the MSI is slightly faster, but in that same review was said that if you are not planning on overclocking there are much better options for GTX 680s. But since there is already a factory overclock on it, I thought it was faster without overclocking it myself. So my question is: which card is better if I don't want to overclock myself?
