user2678: With the return from GPU mining likely to be affected by ASICs, where can miners turn their machines? Should I become a pro gamer? Join a rendering farm for cash (do they exist?) and let Disney use my rig to make toystory 4? Donate it to SETI@HOME or FOLDING@HOME? Donate it to an Anonymous botnet? Join a spamming farm used to bombard Bitcoin dev's with requests to switch double-SHA256 for double-MD5 in the code?
In short, what serious alternatives are their for profit or just putting to good use mining rigs?

user1976: you could mine litecoins; the advantage of having a GPU over a CPU is not as pronouced as with bitcoin but it could still be profitable. you may have to run those numbers though. ltc-charts.com for exchange rates.

user323: Vanity mining for example over at my Vanity Pool. Thanks to split-key vanity addresses anyone can request a vanity address without compromising their security, set their own bounty, and anyone with a mining GPU can try solving the work and claiming the bounty.

user2699: Folding@home can run calculations on your GPU, Seti@home at least support nvidia.
There's also gpugrid.net, which seems to be specialized on using GPUs for medical research.

user85: Unfortunately, none of those other uses are worth the power your GPUs consume. I'd say sell it and use the money to find a new hobby, like skiing or flying model helicopters.
