Hello!

The Impact of Dual-Core Processors on Your Business and IT Strategy
The flexibility, reliability and manageability of Intel processor-based platforms-including the advantages of dual-core and then multi-core processors-will help fuel transformative new business and IT usage models. The following may be helpful as you plan for change.

Explore Transformative Business Solutions—From real-time business interactions to automated asset tracking, the ability of technology to transform business is increasing. Many of these solutions will demand fast throughput for multiple, simultaneous transactions-a perfect fit for Intel dual-core processor-based platforms.

Take Advantage of Increasingly Flexible CPU Resources—In tandem with new virtualization capabilities, dual-core Intel processors will enable very granular allocation of processing power. Plan on using these capabilities to tailor and enhance service levels for multiple applications and complex workloads.

Work to Optimize Datacenter Efficiency—Server virtualization and consolidation, grid computing, and embedded IT capabilities are helping companies simplify their datacenters, improve utilization, and reduce total costs. Dual-core Intel processors will give IT more granular control to support these and other critical advances.
These advantages could answer your needs specifically for

app that has brought my machine to 90% CPU usage (both processors)
I had also tried using good old dual-processor of Intel (dual PIII 500MHz) in server side processing and it is really realiable in Multi-process like RAS SERVER serving dial-up clients (sort of our own version of mini-ISP).

A dual core processor is exactly what it sounds like. It is two processor cores on one die essentially like having a dual processor system in one processor. With the idea that dual-core will also support dual processors (which makes it 4x processing (in general way), well, it is much better to have 4x-core so on and so forth in 1 chip in a very near future. Especially when we both know that Intel and AMD are racing for it.
