I mentioned before that I had upgraded my system from a Intel PII 350/TNT/128 to an AMD Duron/GeForce 2 GTS/128. I basically took out my 2 year old PC 100 memory, my sound card, and Win TV card, and installed them in on my new ABIT KT7. These are 1-2 year old components, and work fine. The only problem I encountered was system lockups during games. I fixed it by installing the VIA drivers the RIGHT WAY, and since then: NOT ONE SINGLE LOCKUP. I didn't experience any BSOD, except for one that involved the Gravis game pad pro drivers, which I was able to fix (this happened on my older Intel BX system, also).
I use my PC for gaming, and also Website development. I use Photoshop 5.5 heavily, PhotoImpact heavily, Video Studio 4.0 for capturing raw, AVI video (then convert it to MPEG 1), Cool Edit Pro for sound reproduction and MP3 conversion, etc. NO PROBLEMS here. You don't need an Intel setup anymore for complete system stability, nor do you need brand new components. Most of the problems that crop up now on an AMD/VIA setup are usually a screwed up configuration (having ACPI installed can/will cause problems with older hardware). I could name several other things, like overclocking incorrectly, cards installed in PCI slot 1, memory sticks in the wrong memory bank, using beta drivers, weak power supply (300 watt should be the norm), funky Windows 98/98 SE/ME/NT/2000 install, jumpers on HD/CD-ROM's set wrong, etc. -- stuff that shouldn't be overlooked on an INTEL system, since the same problems can occur.
I'm will not argue that Intel makes rock stable chipsets and CPU's. I'm just saying that from my recent upgrade experience, AMD is a very viable alternative to Intel, and can save you money that can be spent on a high end video card, more memory, etc. Hell, Alienware and Falcon Northwest -- two HUGE gaming rig makers -- have even made the switch to AMD. If these two HARDCORE, specialized computer gaming rig makers are using them, AMD must be doing something right.
