Ok, what? Just saw this on Craigslist. Had to chuckle.

Here's what you'll get: A Radeon HD 5770 video card (worth about $120) or the 5870 (worth $240).
In exchange, I'll get: Use of some of your electricity via the video card.
I know it sounds weird, but it's for real. Email me for more info.​

Unless he just wants someone to run some kind of folding program at night for him, I'm quite confused.

This. He just wants to use the GPU for a distributed computing app.
lol. People will turn that shit off immediately when they find out you can't game while it's running.

All distributed computing stuff is like that. Running F@H on all of your CPU or GPU cores has a very significant effect on game playability. The most noticeable example I've seen is Ghostbusters. When F@H SMP is running, the game lags really bad and never has a steady frame rate. When F@H is turned off, the game is smooth. I asked about this before and someone said it was caused by cache missing. Even though F@H isn't taking up "compute" time, it's still sitting in the CPU's cache. Less cache available for the game means shittier frame rates.

i kinda doubt a program can just sit in the cache when it is idle priority....aren't applications layers away from dealing with hardware anyways?

Interesting I was looking on Ebay for a video card recently. There's a seller there selling broken and not just defective but physically smashed with a hammer video cards for close to retail. he justifies it as you're investing in something I can't recall what. The whole thing seemed odd and this reminded me of it.

Not sure, but I know for a fact that Ghostbusters is unplayable when F@H is running. If I open task manager, it shows Ghostbusters only using 1 CPU core (50% CPU load). If F@H is closed, Ghostbusters uses both CPU cores (around 60-70% CPU load).
