I previously asked about a general outline for a Linux workstation, and the GPU came up as AMD 7770. Could any of you give me some info on the card's rendering power? I will probably be using Blender (Cycles has GPU rendering support) a lot on Linux, and was wondering if it is a decent card when it comes to OpenCL rendering. My price range for a GPU is not much, as I only have about 600-700 dollars for the parts. So if you have better suggestions, try to keep the price within a reasonable limit/range of the 7770 or so. I will be using an AMD FX Piledriver 8320 or 8350 with 8-32 GB of RAM. Thanks for any light you can shed on this!
