Sure, but it also doesn't pay to purchase a 10Ton truck to move a 1Ton load :)
Bottom line is, you purchase the hardware for the needs that you have.
Not every situation warrents a quad XEON on a blade system. The
problem is, I have another server, with a slower CPU, half the RAM &
a gigabyte motherboard, yet it can handle the same load.

This server runs 4 XEN VPS's, which I moved to the slower machine, and
the slower machines handles the load very well. So, where does the
problem lie? With the "cheap desktop hardware" ? I don't think so.
Rather, I believe there's a hardware problem - i.e. CPU / RAM /
motherboard / PSU?

I have reinstalled the OS (CentOS 5.2), and swapped out the HDD's as
well - so that's not causing the problem.
