The architecture of the Pentium 4 and Pentium D is collectively known as "NetBurst."

Pentium 4 is a family of Intel processors with one core based on the NetBurst architecture, but some types support Hyper-Threading technology that exposes an additional, "virtual" core to the OS.

Core 2 Quad is another kind of Intel processors with four cores, based on the Intel Core architecture.

GenuineIntel = an Intel processor
Family 15 = Netburst architecture (Pentium 4 / D/ Celeron D)
Model 3 = Prescott core
Stepping 4 = Processor-specific revision number; not terribly useful in most cases

Based on this information, you likely have an Intel Pentium 4 3.00 GHz processor.

A few new sockets came out with Pentium 4. I know 423, 478, and 775 were used during this time.

It was based on the Netburst architecture, which was new with this version of Pentium. Northwood was one of the new revisions of pentium 4, that's new too.

The most gaping new technology was HTT. Hyperthreading Technology, which actually did not premier with the Pentium 4, but was developed late in the life of P4, and applied for the first time here.

It should be fine. Before someone says its based on old Pentium technology, it isn't. The new Intel Pentium Dual Core processors are based on the Core 2 Duo core architecture (Merom-2M).

However it doesnt share the same amount of cache as the Core 2 Duo laptop versions have. Although I have one for my new laptop which I use for basic work each day. I have a proper desktop PC which I use to play games and such.

But expect the same technology and enhancements you see on the Core 2 Duo to be on the Pentium Dual-Core.
