Anyone at all using X3 Producer with Windows XP SP 1?

Anyone at all using X3 Producer with Windows XP SP 1?
I can upgrade my OS to SP3 the latest.
 
I know it is no longer officially supported , but does it work anyways

Thanks amigo, Yes my daw is 10 years old, and I figured exactly what you posted above. If I was to get a new computer for audio work I would certainly build it myself with a half hour or an hour purchase of Jim Roseberry's time http://www.studiocat.com/open_cart/ (or actually purchasing one of his builds). It would be my 4th build although I have not done it since my Core2Duo office computer in whatever year I built it. My current DAW is as old as mud, a Pentium 4 Northwood running 8.5.3 producer.

Building them is fun, and pretty pain-free these days.
 
Make sure your new motherboard has both USB 2 and USB 3 ports, as some/many audio interfaces that have USB connections do not like to be plugged into USB 3 ports.
 
I would suggest some flavor of i7 CPU, and 16 GB of memory, or 32 GB if you have any money left over - but 16 is still good, so don't kill yourself trying to get 32 GB.  I have used AMD CPU's several times over the years, and they have good value, but I find the Intel chips to be a bit faster.
 
Also, my initial build of my latest computer had 2 crazy powerful video cards, but since then I have gotten rid of both and simply use the on-board graphics - and that works just fine to drive 2 giant displays (32" HDTV and 46" HDTV), so I would suggest you hold off on an expensive video card - you can always add one if needed, for between $30-$100 that will be fine.
 
I also had a 512 GB SSD drive when they were first available - almost $500, and it bit the dust, but while still under warranty.  That refund is what bought my 46' HDTV that is now my primary display, and the hard drive is now a run if the mill 2 TB SATA III non-SSD drive, that only ran something like $79 or $99, can't remember.  That drive is plenty fast enough for streaming.  Do NOT get a 'Green' drive, you are a POWER USER, and the variable-speed drives are a giant headache for Sonar - get drives that spin at 7,200 RPM and you will be fine.  
 
You will want at least 2 drives - I recommend a 120 GB SSD primary drive, for the OS and your applications only, which will be crazy fast.  I also recommend at least one additional drive, SATA III 2 TB (almost same cost as 1 TB so go ahead and get double the size for like $10 difference).  This second drive should hold your projects.  Some folks pick up an additional drive for holding sample libraries and such - I keep all of that on my 2nd drive (the same one as the Cakewalk projects and audio), and I have never had any performance issues just using 2 drives.  I actually do NOT have a solid-state drive as my primary, and still don't have performance issues, but the SSD drives are lightening-fast for holding the OS, and if I were to build another computer, it would have an SSD drive for the primary drive.
 
Anyways, I hope any of that helps.
