Coincidentally I have a similar setup, WCG is a non brainer due to payout from Byteball (although that is no longer paying as much as before). Deciding on Seti was based on its relatively lower team RAC, but it has a higher number of team members; so not sure if that is the right project to load GPU with? There isn't much GPU project choices and RAC stats between them varies widely, (maybe each gpu applications have different efficiency), other than trying each project with different hardware, not sure what is the right heroristic to use for GPU computing?
