Having browsed some reviews, it seems that the GPU compute performance (GPGPU applications, CUDA and the like) is significantly worse than a GTX580. I was thinking of upgrading my GTX480, but I need both double prec. GPU compute perf (for CUDA simulations) and a good gaming experience (for me . Anandtech pretty much confirms the sacrifice of GPU compute perf for gaming performance in Kepler. Although they (or someone…can't remember where I say that) hint that there may be a later generational update which adds some back? Also, the drivers could be optimized somewhat more. I'll wait to see what happens….
