Upgrade to Sonar 5 from Sonar 2??

I've seen some posts in the past touch on these things, but I have a couple questions. Cakewalk just started a deal to get Sonar 5 (Studio) for $79 ($20 off normal price). I'm currently using Sonar 2. My system specs:
- AthlonXP 1700
- 512MB RAM
- multiple hard drives
- WinXP Prof
- EMU 1616M card

1 - Given my system specs (that seem to barely meet system requirements according to Cakewalk's website) would you recommend upgrading to v5 Studio? I have no problems with Sonar 2 for what I use it for.
2 - Has anyone found any issues running v5 on a 32-bit OS?
Thanks.

I believe that you will be fine running Sonar 5 on Windows XP. The vast majority of users are still running the 32-bit version of Windows and I believe there are lots of folks using Sonar 5 on it. As to whether you need it? Probably not, altough the Sonitus effects come with Studio now, so that is rather compelling. I still use Sonar 1.31 and I will be ordering version 5 quite shortly to mix an album. My primary interests lie in the Sonitus effects, the ability to export broadcast wave files, and other mixing niceties that version 5 brings to the game. Other than that, Sonar 1 records audio just fine for me.

I use a 1.8 Ghz Pentium 4. V-vocal and Perfect Space would definitely bring things to a crawl fairly quickly, but the core program runs fairly effeciently even with it's enhancements - I think I can handle about as many of the same effects now as I did when I started with Sonar 3.

If your pc is trimmed for audio you can do it.
Sonar doesn't use much horsepower or memory
It's the plugins.
Sonitus aren't CPU hogs, at all.

"Mastering" plugins and Synths are the reason for more CPU and memory.

I don't know how you survived this long without the bussing improvements in S3.
