and games will start requiring a dual core.
They will? So you won't be able to use a single core AT ALL? Will regular apps like MS Office require a dual core? When will this all happen? I'm hoping that I don't regret buying an A64 3700+ Sandy.
I don't think we'll see any products requiring multi-core any time soon. What you will see are games running in two or more processes, something that doesn't happen (much?) today. IF a game launches two processes, on the 3700+ they run on the same core. If the game does the same thing on a 3800 X2, the OS can assign the processes to different cores. Either way, the app should still run.
