Wow, you're not hard to please are you... lol
Changing topics however, seems like that 5870 is cranking out some good credits. I don't have that GX280 running any CPU projects either, it seems to slow it down when I do.
But on another note, perhaps these GX280's aren't as worthless as I said and they can be redeemed. I found a place in town that looks like I can literally buy a pallet of them. Now I'm thinking I might pursue a train of thought with these things and look into building just GPU crunchers.
