Here is an example I found for a 20,000 lb shipment of telecom boards. After refining and shipping fees are deducted, the net value is $7.95/lb. I think for pc motherboards the value would be lower. I think this is a pretty realistic example, you can see that some of the larger ewaste buyers who deal with the refiners directly don't make an absolute killing on this stuff:
Forgot to add that this is a few years old and metal prices were lower then. However I'm sure refining costs are also higher now, so in the end it probably won't be a lot different.
