You can get a Celeron or Pentium Dual Core nowadays for around RM200 or less, which are much faster than your Pentium D.
Motherboard and processor manufacturers always have to change something (new chipset, new socket, new processor, new VRM, etc), otherwise cannot "cari makan". For example: make new processor but can use on older motherboards means they can't sell much of their new chipsets. Usually new processors would coincide with the launch a new chipset. Backward compatibility is always welcomed though new features such as better power management, new bus signalling, integration of memory controller, GPU integration and/or change in memory controller would sometimes bring about a new socket (like LGA1155). Of course they also have to bring some improvements and new stuff into the mix (e.g. USB 3.0, SATA 3.0, LightSpeed, AVX, etc). Right now the problem is that software needs to play catch up..

At first thanks for the recommendation of the Celeron and Pentium processor. I am very well aware that they are faster than my silly Pentium D.

But no, I am more happily to take Core 2 Quad for <RM200 2 years later.

my pentium D is fast enough to my everyday job it is idle mostly due to I am only using web surfing, light applications.
IMO, the practicality of new improvement is really depends on individual. Unlike olden days where every gen of CPU actually make ur daily task faster. Right now if u are not dealing with Multimedia Editing, VideoGames even a 5 years old PC can still do a decent job without any lagging.
for example
Sata 3.0 is overrated, HDD are not gonna be using all that bandwidth, they are not fast enough for even Sata 2. USB3.0? I dont often use my external HDD. It is only the external HDD that is bottleneck by the USB transfer speed.
I think my only concern is the reliability of a motherboard. Because if a old motherboard is down, every old standard/socket devices you have become unusable with any new motherboard.
(I got 3 AGP gfx cards in my drawer now after 4 dead motherboards
) Thankfully the new motherboard are coming with good quality component, solid cap/mosfet etc. or whatever gimmicks things they are selling now, at least they are more reliable than the older generations.
Yes, software need to catch up, so until the software can come up something useful like 99% reliable voice recognition(the old keyboard/mouse combo need to be gone), language translator or a computer that think for u. (AI), that I need a powerful CPU to do it. Then may be I might be paying RM1000+ for a CPU. Right now I think there is no way I will pay> RM250 for a CPU, the same could say for GPU, HDD, optical drives etc.
