I'm doing some folding again, since December, after quite a long break. Got myself PS3 at first, thought I might try F@H on it, and I left it working while I was not gamng. Later I added an otherwise bored quad-core Xeon server. Only recently, I added one more SMP client on virtual machine and GPU on my desktop with Radeon HD4850, when I'm not gaming and the PC is on (mostly evenings).
Also, the new client 7.1.24 works nice
...too bad HD4850 does not work with new OpenCL core
