I plan on getting an iMac for audio production, so I will be getting the i7 CPU, but the GPU is meaningless for audio. However, I also want to be able to play modern games at the best possible settings for as many years as possible. Using the iMac would be cheaper than building a separate gaming rig, assuming the iMac can handle it. How much of a difference will the 395X make over the 395 for gaming? My original thought was to go all out since the computer is so expensive anyway, but if I'm not going to be able to play modern games on high settings with over 30 FPS even with the 395X, I'd rather just save $250, take the standard 395 GPU, and build a gaming PC separate. Any thoughts on this?
