I have an ancient PC with the ATI Radeon 4800 GPU.
Are there any projects within or without BOINC
that would have work units for this GPU?
I am ready to pull the GPU because it uses 55 watts
(for nothing) while my p.c. is on.
Maybe try Collatz? The OS also matters, because you will need to download drivers straight from AMD in order for OpenCL to work.
IMHO, pull it out and hold on to it until it's an ebay collector's item and worth $$$$. Unless you're getting your power for free, it's a lot of energy for very little output. GPU performance (and performance per watt) has consistently progressed with amazing speed vs. CPUs.
