Funny you say I need a reality check, when it is you who is about to get one.
My opinion stems from experience - I've been using Radeons since the beginning of the name. They've always been tops for all-around work in my rigs. They work well clocked low, clocked high, with or without software accompanying the drivers, unlike nV. Even AMD's HD-series onboard will accelerate CAD nicely. I don't just game, which is what the loudest of whiners about this card seem to do. AMD's GPUs have consistently proven to me to be superior for all-around work. If I wanted a GPU just for gaming I'd buy a console, and nice, they have Radeons, too.
I've had more than enough bad experiences with nV as a company during my years in Silicon Valley, with their GPUs at times when I've tried using them for my diverse workload, and with their software when it attempts to dictate to me what hardware I should have in my PC via BSOD.
You've made clear your pro-nV leanings in many threads. That's fine. Maybe you'll be original one day.
