Hey guys,
 
One reason I've held off from upgrading to Platinum and stuck with X3 Producer is some slight intimidation at the rate of updates. I don't have a state-of-the-art PC by any measure, but for X3, it runs smoothly enough. I'm concerned that if I made the jump to Platinum, that my system's specs would quickly (if not immediately) be rendered obsolete by the frequency of Sonar's updates.
 
Like many, I can't exactly afford to upgrade my computer or its components once a month, or even once a year. So I'd be wary of switching to the current version of Sonar if it means not being able to run it on my system now or in a matter of mere months.
 
I'm hoping my fears are misplaced. Are the updates not as impactful on system resource demand as I might imagine? And is there a big (if any) jump in resource usage from X3 to Platinum in general?
 
Any insight is greatly appreciated!

FWIW, I'm currently running a first gen i7, the better performance that I'm getting with SPlat (first on W7 and now on W10) has allowed me to put off/deferred upgrading my hardware to a new i7 by at least a year.

This is a very original question. I run a q6600 and have actually seen better performance with Platinum. Note, this is running Windows 10 64 bit.  
 
 

Similar to John ...
 
I'm running the same machine I bought when I was on X3e.  I upgraded to platinum as soon as it came out and have stayed current since.  My experience is that performance is better with Platinum than X3e with the same machine.
 
Also, you decide when you want to apply updates regardless of the frequency with which they become available.  The updates are cumulative, so you install every other, every third, or every whatever update - it's whatever you feel comfy with.  PLUS, if you do install an update that causes performance or other problems, the Rollback feature can be used to step back.  I have slammed the Hey Zeus! out of Rollback just to get confidence in it.  It has been flawless.
 
Seriously, Platinum has allowed me to delay new hardware instead of increasing my need for it.
 
As always, YMMV 

Check my signature - although I should add EWCC and SPlat latest version to it.

Low spec, sometimes slow, but it works fine.

My DAW is nearly 3 years old now so I was on X3 when I built it. There have been a number of performance improvements and optimizations in Platinum so it seems to require less CPU than X3 did.

You will get much better performance in platinum on the exact same hardware than you get in SONAR X3 or earlier.
Here are just a few of the updates that feature the great optimizations in Platinum, but we're continually making the software faster and more streamlined.

Same here. 8-year-old Q6600 with 8GB RAM, runs Platinum quite nicely, I'd say (as Noel details above) rather better than any of the X series ever ran on it. Certainly it's more stable, and more enjoyable to use in so many ways. If a project gets very complicated I have to either do some freezing or run pretty high latency for mixing, but for basic day-to-day purposes I can work quite well with it - so much so that I'm looking to replace the system drive with a SSD and see if I can squeeze a few more years out of it before I need to join the modern era!

upgraded disks to SSD, added 4GB RAM. starting to run a bit slow when i have more than 20 tracks with effects. but SPLAT definitely improved performance overall.

Just to "+1" the above, check the specs in my signature.
