Yes, I have had a few GPUs in personal computers pointed at BTG (when not being gamed on) on Suprnova pool since it launched and there have been no problems at all. Most pools seem to have been a horror story the first couple of days, but Suprnova was rock solid all along and has paid out like clockwork.  BTG is worth mining for daily profit, but there's also a chance it takes off down the road if you want to just hold them for a few months.
