Since i'm new to this just wondering what kind of ppd i should be expecting from i7 oc to 3.8ghz and from my 2 gtx 460s? at the moment im getting just short of 10k for the gtx 460s and unsure about the i7 as it hasnt appeared on hfm.net as it takes up to 40mins just to do 1% if thats normal? also when i run the gpu clients i get a high pitched sound coming from the gtx's but only when I run it, and it doesn't seem to be related to the fan as i have tried lowering/increasing fan speed, so unsure why it is happening
