before the quad core comes the hard drive, and if you think you can run a virus scan or encode a video while you are playing, you are dreaming my friend. the first bottleneck is the IDE/sata bus, and this will impact you whole computer when its being use intensively.
so yes, quad core is useful for speeding up multi threaded applications, but dont think that it allows such flexibility with multitasking. your tasks cannot be hard drive intensive, otherwise your performance will be hurt. and frankly, I cant think of anything that I would be doing while playing a game that is not hard drive intensive

Unfortunately, memory bandwidth is also a problem in many applications... I.e. even if you don't need to do much HD I/O, you have to be able to supply the four cores with the data that they're crunching.

With quad-core K10 chips, that shouldn't be much of a problem. They will probably be bandwidth-saturated by DDR2-1066, if not DDR2-800.

Memory bandwidth will only become an issue in the unlikely event that all four cores are running memory intensive threads under full load. Additionally, K10's improved IMC and L3 will likely reduce the impact of insufficient memory bandwidth in the afore mentioned case.

It's good to see them being released. And the fact that most of us X2 users can simply replace our dual-core cpu's with a barcelona is great news.

I'll replace my X2 when the AMD quad's hit 2.4-2.6GHz range

I have encoded a dvd while playing bf2142 and not noticed a hiccup and this is on a e6600. Just set the affinity to different cores.
