cfc, Home and Pro support dual-core - anthough i admit i'm not 100% positive on that so i'd wait for confirmation first.
Interesting posting i found on another site though.
Can Windows Handle Dual Core?
The primary element to focus on is Symmetric Multi-Processing (SMP). That is where multiple processors can perform concurrent tasks. SMP capabilities are software-driven, which means applications must be SMP-aware to benefit from multiple-processor systems such as dual-core.
Herein lies the biggest obstacle, as many operating systems, such as Windows XP Home, are not SMP-capable and will not make use of the second physical processor. Also, most modern programs are single-threaded, meaning there’s only a single current set of linked instructions. As a result, only one processor can effectively work with those single-threaded applications.
So does this mean that the typical system builder should abandon dual-core processors? No! The key is to use dual-core based systems to build lower-cost, high-end workstations and entertainment PCs.
Why those particular systems? Because applications exist in those environments that can leverage SMP functionality. Graphics applications such as Photoshop, and CAD applications such as AutoCAD, thrive in multiprocessor environments. Also, OSes including Windows XP Professional can benefit from SMP-compatible systems, as well as Windows XP Media Center Edition. Finally, several high-end games can benefit from SMP, especially when it comes to rendering graphics and maintaining frame rates.
As they say, the proof of the pudding is in the eating. So let’s build a dual-core system and run some benchmarks to determine what improvements a system builder can expect.

Thing is are you really going to benefit that much from running dual core?
