Ready For The 64 Bit Future
A quick look at the functions that the Pentium D 805 supports should convince you that it's not old hardware - it still has a viable future ahead of it:

When compared with the most current models, this CPU doesn't miss any of the important features. Support for both EM64T (64 bit instructions and execution) and the Execute-Disable function (NX) are both present. The Pentium D 805 is a dual core architecture, so it can do without Hyper Threading and not take too big a penalty. The only new feature that's missing that might be of some concern is Intel's Virtualization Technology (VT). This reflects Intel's well-known practice of building only a single core, but then deactivating various functions to serve different price segments.
