Even though the socket is the same, the BIOS and chipset calls the shots when it comes to the CPU. While the Quad core will fit in the socket, its not gonna work.
The max RAM on the 800 series is 4 gigs too. I've done the research and was disappointed to find that out. The 500 series DOES support up to 8 gigs.
What you may want to look at is the max cpu that the board supports, then consider overclocking it a bit. It can be done, but you will end up with more heat and fan noise and possibly bave to come up with a more agressive cooling solution.
Waverider has a good post about the CPU and the Video card. You should read it if you haven't already.
