GPU for simulation June 14, 2015, 12:08 p.m.

Hi, everyone!
My question for you - What GPU to buy for simulation in houdini?
I can take Tesla k20 (very cheap ~ 900 $) and i don't know worth it or not. For that price now sold more cards (Titan, Geforce) with similar specifications CUDA number of processors, memory speed and other parameters. The price about ~ $ 1200. But they are already on the new chipsets. Is the difference in performance between these cards? And if buy Quadro k4000 or k5000 for Tesla to make “Maximus”, will accelerate the simulation? I'm talking about opencl. Simulation smoke, fire (pyro) and flip.

Today I'm testing my Geforce 670 on smoke sphere. With the grid 300x300x300, Houdini gives an error “OpenCL Exception: clEnqueueNDRangeKernel (-4)”. Latest drivers does not helped. There is a sense in this idea simulation with the GPU? If configure a complex scene with fire and smoke in grid 1000x1000x1000 or more, it be correct considered with Tesla or Titan without errors like OpenCL Exception: clEnqueueNDRangeKernel (-4)?

p.s. sorry for my english :roll:
