PCI express revisited

Test results with the new generation, i.e. GT 200 based and PCIe Generation 2.0 with doubled performance, show that general naive implemented copys do not get any speedups.
Blocked copys however, climb up to 4.5 GB/s when writing data to GPU memory.
Data copy back to the host is still relatively low at 2 GB/s.
