I'm also wondering if Sonar will support my Windows for workgroups machine. I have optimised HIMEM.SYS and Quemm is installed so I can access at least 600k base memory.

but I doubt you have a dual layer dvd for it, or a net connection .. and dialup .. well bit long winded

Option #3: use DAW software that is supported on XP. Probably the cheapest route. Or, if you're going the route of new hardware, do what I did... get a good deal on a late 2011 MacBook Pro... keep your options open for when MS makes some totally bizarre decision to do something wacky with their OS. :)
" Support for Windows XP is ending on April 8, 2014. If you're running this version after support ends, you won't get security updates for Windows."
Shame CW is throwing the baby out with the bath water, for the sake of what.. maybe 5-10% of users ever using the unique facilities of Win8? Fewer OSes = cheaper dev cycles and all that... but let's not pretend that the inertia that the broad market has shown wrt. moving from XP doesn't exist... still. If MS -- of all vendors -- officially supports XP, so too should ISVs that want to play the MS game.
use a DAW that still uses xp.. until a point.... remember the most expensive cost of software is maintenance, when it starts becoming a bigger hassle.. other makers will drop it as well.
Funny you say about Mac.. these are the same lot that changed CPU and pretty much force a friend to buy a new machine to support a new version of logic. Also remember when certain older os X plugins didn't work with newer version of the OS ? I do ;-) .. my friends bored me about it and I told em get a pc.
if they ran a poll of how many x1 / x2 users were still using xp ? , heck why don't they still support win 98 se. No one is forced to upgrade their studio, continually.
I still wonder how old the OP's sound cards are.. as no model was mentioned. I still use an sw1000xg (12 year old card).. but it's only for midi, and the driver side is bad for the audio.
