Hi guys, I came from a late 2008 Mac Pro 2.8 Quad Core Intel Core Duo with 10 gigs of ram and 1GB 5870. I just took my HD and graphics card out of my old 2008 Pro and put it in this new Pro and turned it on. It honestly seems slow...or even slower than my 08 model. Does this make any sense? I have the latest software updates and OS.
