I don't get it. One thread has posters disappointed with the R9 M295X performance on some game benchmarks and others are impressed. Some say it's no better than a two-year-old GPU -- except they overlook that it can push a 5k monitor. Some people say to wait until the next rev -- possibly another year away. Some say get the 295 instead of the 290. Max out the iMac to make sure. Wait until next year. What's a normal Joe to do? My early 2008 2.66 GHz Intel Core 2 Duo is getting long in the tooth. I use Photoshop, Aperture, Lightroom and Illustrator regularly to help create my artwork. Problem is, I'm pushing my little guy, and Photoshop takes longer than it should and big documents with multiple layers freeze me up. Heck, even launching Bridge messes me up. So, I was looking forward to this update. Do I need a 5k screen? Probably not. But I know it would be nice on my eyes, and photo editing would be less of a strain. Do I game? Aside from Civilization, I game on a One. But what in the heck am I supposed to do? Wait another year? I don't want to. I also don't want to blow $2,500 on an old model 27" iMac when I can spend the same, or close, on a 5k with basic CPU and GPU (educator discount and all), but some say I'd be throwing money away on a system that soon would be outdated. I'm eagerly awaiting real-world tests. Any advice from the sage MacRumors commentators?
