Haven't been following these graphics threads much, and a bit behind on the current state of GPUs. However, most of the reviews of GPUs seem to be around gaming performance and what-not. But that's not the only reason to get a nice GPU. Personally, I upgrade dot the 395x because I want to ensure I can comfortably drive several high-res displays. Currently, I'll only be pushing a 5k and two 2.5 Ks, but I may be upgrading my external displays at some point. When I do, I just want to ensure that everything flows fluidly, and without lag. I know that the new 5k supports two external 4k, just not sure they can both be at 60z. And that's my desire.
Anyhow, does gaming performance always correlate with diving more pixels for non gaming kinds of tasks? I seem to remember reading, number a years ago, about how workstation and gaming GPU values weren't always aligned. That some GPUs that were screamers at gaming things didn't do as good of a job with lots of pixels.
This is not something I'm asserting, just something I'd like to know. Could it be that Apple chose this line of GPUs for their ability to better support pros driving lots of pixels for work applications, instead of people trying to play games? Just wondering...?
