crunchgear.com— Thought Two Cores was enough? It isn’t. Really. Intel confirmed today that they will be releasing a 2.67 GHz quad-core Core 2 Extreme this holiday season. Drooling, yet?

The performance increase wouldnt be much. When you put two cores on a single front side bus, depending on the application, they can fairly easily be bottlenecked by memory bandwidth. Drop for cores on that same FSB, and they will be choked for memory bandwidth. Same principle as why Intel server platforms scale very poorly beyond 2 CPUs.
Having installed XP on a dual proc, dual core Xeon machine, I can tell you right now that XP DOES NOT SUPPORT TWO PHYSICAL PROCESSORS THAT HAVE A TOTAL OF FOUR PHYSICAL CORES, period, case closed. So---yer wrong there, bud.Do dig me down though.
my Pentium 4 is looking pretty old now. I doubt i will get a quad core processor anytime soon because they don't seem like it is worth the money for something that wont really give you a boost in power. I think I will be fine with the core 2 duo chips, I'm just waiting until dell has them in there laptops. Anyone know when that is going to happen?
Actually XP Home does fully support hyperthreading. With the latest service pack, Home is as compatible with hyperthreaded and dual core processors as Pro is. Theoretically, it should also support a single physical chip with 4 cores, as it is still only ONE physical chip, which is the limitation.

AMD is still better

I Also didn't realize the Nintendo 64 was only 2 years old!
