Percisly, thats where you would use an Xeon or Opteron. But for a system that would be used for video editing, for example, you would not use a server motherboard & CPU.
=Ahh, but we are not talking about the "end user", We are talking about large company's that need a very fast central server (maybe the schools should take a lesson in that, instead of the slow as shit ones my school has =.=), but your right, the average user cannot use a server mobo & CPU. But this is just proving the point that CPU's with more than 4 cores can be useful.

Well, then those apps don't need 6 cores. But the apps for industry pros can utilize 6 cores, many can handle more than that. For instance there is a motherboard out that can hold 4 AMD processors, with 6 cores each. Thats 24 cores, and apps can utilize those too. Of Course, the average windows system cannot utilize more than 1 CPU, but thats beside the point. http://www.pugetsystems.com/part_info.php?part=6643 http://www.pugetsystems.com/part_info.php?part=6655
Well, ATi is known for their iffy drivers, trust me, the 5xxx drivers were terrible (for me at least) before the latest release. You may want to check the C&C forums to see if anyone else has the issue.
You don't need it for gaming, but for CPU intense things, I'm sure you could find a good use for 6 cores. P.S. AMD's response is coming soon, they already have engineering samples of a Phenom II x6 out.
