|I've never done this before with any OS so I'm a little wary in general.
|But I have a P3 800 that I'm thinking of upgrading as prices are really
|low and I have a little money right now. Is it a fairly trouble-free
|process to install a new motherboard/CPU on an existing install or do you
|have to reinstall the OS? As I've never done this before I have no idea
|how it will turn out, if SuSE will recognize the new hardware and just
|deal with it or if it will be looking for old hardware when it boots and
|be unable to readjust. Thoughts on this?

You shouldn't have to reinstall. YaST can adjust. You may have to go in
and clear out old settings and redetect, particularly for the NIC. Might
be an idea to disable the old NIC before swapping mobos so it won't
spend time trying to make a network connection after switching on with
the new NIC. Also you may first have to reconfigure the X server with
sax2, especially if the video is onboard. So be prepared if necessary
to boot in safe mode, or even to console mode and then run sax2. Of
course if you are moving the video card over, that's not an issue.

That's assuming you are not running a processors specific kernel. Prior
to 9.1, there were optimised kernels for Athlon, etc. so if you are
changing processor lines, you might have to boot a generic kernel first,
then install the kernel package suited for your processor.

|Also, if I decide to do it, is there any advantage to going 64bit?
|Obviously that would require a reinstall, but I'm curious, though. Since I
|have a 64-bit OS it's pretty tempting. Are there any performance gains to
|be had over 32-bit? For help in answering this I'm a java/web/database
|developer. So that + reading email, ripping MP3s, burning CDs, browsing,
|etc. are what I mainly use this computer for. Any advice is appreciated.

You'd have to read the reviews but I suspect you won't notice the
difference. I looked at the offerings and IMO it's CPU hungry users who
want every bit of speed who are willing to pay the premium. I'll wait
until the technology is a bit further along the curve. There are fewer
motherboard manufacturers with a 64-bit line which means it has yet to
mature. AMD has released the Sempron series to bridge the 32 bit and 64
bit processor lines; that should encourage the transition.
