Right, good news/bad news...
Bad news is that I'm retiring my 9800GTX+ from folding, at it's peak it used to give me ~6k PPD alone, but ever since the old 1.09 FahCore it's just not been GPU2 stable, even at default clocks (obviously 3D stable though, but folding does stress them more indeed).
So I shall be donating this card to a friend as a gaming card, which it's perfectly fine for (and still bloody fast..!).
Good news is that I've just ordered a Leadtek GTX 285...!!
So I should be looking at ~9k PPD from that monster alone...

, I was tempted to go for the GTX 295, but that seemed like too much overkill for my little mATX box.
So hopefully I should start hitting some decent production by the middle of next week, looking forward to it.
