Well my bottom fell out too because it seems as though the new driver is not playing nice with any 460 let alone both of mine on the smaller wu's things were plugging away fine at the start once the bigger wu's came back backed the clocks down on the 460's and perhaps I was pushing the limits of my hx750 with 2 460 768's and a 560ti and my oc'd 930 heat was not an issue altough it's probably something easy as i'm still quick sick and congested with no real mental capacity to start to safely trouble shoot without running the risk of sneezing all over computer components
I removed the 1 460 now both cards running 6801's 560 is getting 14.5k 460 is 3500k I'm open to suggestions and will return the favor in some form
