Hiya :-)
Currently have these GPU's and CPU's running Boinc projects:
(2) GTX 980 Ti's (1 K|ngP|n, 1 Classi)
(1) GTX 780
(1) GTX 960 (4GB)
(1) GTX 950
(1) GTX 1050 (4GB) *intermittently*
(1) i7-6850k (@ 4.2)
(1) i7-7700
(1) i5-7300qs *intermittently*
The PPD is pretty darn good for GPU accelerated projects.
I recently acquired an E5-2683 v3 and need a C612 mobo to run it, if anyone has a reasonably priced on, please let me know.
