Right, first a bit of background. On the ATI Radeon 4770 thread, we have this posted followed by this (among others) now, apart from the fact that I tend to agree with Jenny_Y8S and find smc8788's comment rather inflammatory, I have taken his/her advice and posted this comment here, because I honestly want to know the answer. The way I see it is this. If you have a processor, that you have paid for anyway and is on anyway, then you aren't losing much and are potentially helping someone by folding. If you are creating a computer specifically for folding you are spending money and electricity on your own personal mini supercomputer. Now, because this isn't actually a supercomputer, it will be less efficient than a supercomputer and so instead of funding an organisation who is doing high-powered research into whatever diseases, you are diverting funding somewhere less efficient and burning up more energy as a byproduct. Bearing this in mind, why do people fold? It seems to me that you would be better off donating your money elsewhere and not having a load of potentially noisy, heat generating machines on your home, unless you just do it for the rankings, which is incredibly vain. I do fold myself btw, the influx of enthusiastic CPC folders got me started and I do think it is a worthwhile thing for my computer to be doing whilst I am out.
