I just went front an old MP 1,1 to a newer and leaner MP 4,1. The old MP1,1 had been fully loaded with 16GB of RAM, 2 Quad Core 3 GHz CPUs and a GTX570 card and was sucking a lot of power from the wall socket. The MP4,1 with a single 3.33GHz hex CPU is much more efficient. It turns out none of the apps I routinely use (Lightroom mostly) benefit from GPU processing so I decided to resell the GTX570 and stick to the GT120 for the time being. Should I still want to go for a bit of GPU acceleration (I am tempted to play a bit with Resolve if I find the time for video editing), what would be a more efficient solution?
