http://barefeats.com/imac5k7.html Anyone notice this? I still think it's criminal that they name the "mobil" versions of GPUs the same as a desktop card that they are VASTLY inferior too. Anyhow, the GTX780 did quite well. The R9 290X did well in OpenCl. We have some early work done on R9 290X, I will only mention that we can enable PCIE 2.0. (Have offered to upgrade Rob's with that for future testing) Have another R9 290X surprise coming, but it isn't my baby so I'll remain quiet for now. Not bad considering that the Pros are on older tech. Amazing how useful being able to stuff newer bits in can be.
