    Does PCI-e 1.1 affect the OpenCL performance?

      PCI-e 2.0 doubles the bandwidth of PCI-e 1.1 standard. It's known that in most cases it doesn't really affect the card performance as the old one hasn't been yet exhausted by the applications. However I suppose that Stream technology and OpenCL may be more bandwidth-hungry than standard graphical application.

      Would placing Radeon 5570 in an old PCI-e slot limit its OpenCL/Ati Stream performance?
