Thank you very much for the response.
If there were a benchmark on benchmark results, it would be very poor. There are countless examples of where the benchmarks are not reliable, that is why I was leaning towards an AMD card based on actual user input. Just did not know if Nvidia had improved on their later models for OpenCL.
I will take your advice on the 290/290x.
A few more questions:
Is there a particular brand you recommend or one I should stay away from.
Are there any power or heat considerations based on the DIY 11 build.
Thanks Again
