I'd say you're good for a while. I plan to run mine for another 3 or so years.
- You're at the top end of CPUs for that socket but with the potential to OC down the road
- Can SLI if needed (mobo and psu are suitable) or get a faster single card later
- Room for two more sticks of RAM
- Reasonable array of USB and SATA connectivity
So yeah - very nice
Only thing I can see is if you use firewire for your video equipment you're out of luck with that mobo.
