I stopped actively folding a while ago after about 4 years of constant upkeep of my farm and clients. I figured if I was going to fold I should be taking full advantage of the hardware so I moved over to Beta clients. With them constantly expiring and otherwise inexplicably stopping I had enough of it.
With that said, how are they now days? I have an i7 rig, some quad and dual core setups along with 3 high end nvidia cards and 2 high end ATI cards that I wouldn't mind getting folding. Do they still expire, how long do they last between expiring? Are there still cleanup issues, as in after expiring you have to scrub files out of the system in order for the new install to function properly?
