For what it's worth, it is my belief that the real hit would be from CPU processing on the systems more-so than the rendering of the 777 object so long as it's modeled well. I do not even know if or how big a FPS hit the systems modeling may end up being either, but Philipp tends to know what he's doing with optimization. There are a number of factors to consider when purchasing a video card. For starters, what size of a monitor will you be connecting this to? I have to admit, my upgrade process has been: ATI 5870, Nvidia 580, Nvidia 680. The NV side has kicked the snot out of my ATI experience each and every time. I'm honestly impartial to either brand...just want to have what always works best! I know that the 680 is expensive, but consider how long it will LAST! That is where your investment comes in. Anyhow, let's figure out your current specs before we push further in this discussion...
