Can someone recommend a good video card to use with CentOS 6.6 that has
a GPU, or two, or more, that will work with the Folding At Home project.
I built a killer machine primarily for contributing to the FAH effort
but the video card, NVIDIA Corporation G94 [GeForce 9600 GT], I had on
hand is not getting any assignments. I'm using the proprietary NVIDIA
driver. I've got a pcie 16X socket to plug it into.
I tried also to run a GPU queue with FAH and it seems that the client program needs a
newer libc library than available in C6.
The logs were not helpfull:

I have discovered the real error only after manually running the command listed in logs
with strace:

I have to investigate if there is a alternate fahclient (older version maybe) which works
in C6

PS: I have seen that the FAH executable for cpu queue is statically linked:
file
/var/lib/fahclient/cores/web.stanford.edu/~pande/Linux/AMD64/Core_a4.fah/FahCore_a4
/var/lib/fahclient/cores/web.stanford.edu/~pande/Linux/AMD64/Core_a4.fah/FahCore_a4: ELF
64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, for GNU/Linux 2.6.15,
stripped
