Maybe he wants really good timings?

Also Freelancer, PSUs are always emitting a high pitched frequency. Under load or due to age, it tends to get louder (as it approaches audible range of humans). A better quality PSU can fix this though. I would swap the PSU, since the GTX285 uses a lot more power than the 8800GTX did. Hearing a whine in a PSU to me is a sign that it is getting old and needs replacing, since system crashes usually follow not to long after you start hearing the whining.
