In this article I take a look at the relative performance differences between the Nvidia 670 FTW, 780 SuperClock and the 780 ti as it pertains to Flight Simulator X (FSX). I'll also include some non-fsx benchmarks for comparing how these three cards stack up. This project began as an attempt to get a boost in performance in FSX from my original card which was the 670. In the end I settled on the 780ti.
