I currently have a Saphire HD 7990, and have been considering selling it to buy a 780ti Classified. The main reason for this is because Im looking to pick up a G-sync monitor when they drop. My question is would I be able to see a noticeable difference in my gameplay at 1080p after I have overclocked the 780ti? Also is there anywhere I can find benchmarks for these two cards against each other specifically because I have not been able to find a good comparison.
