FWIW, I'm running SPlat on a Q9300 (2.5 GHz) with 8GB RAM. Every single project. The machine has limitations for sure, but SPlat does not seem to care any more than previous versions. Obviously YMMV but for me it's just more of the same, in a good way. 
Hello Steve , I didn't mean to leave you hanging and I sure appreciate you telling me your experience ....

I got sidelined doing some major car repairs . After I sprang for a brand new radiator , a bunch of other parts and 5 hours labor to a very good mechanic ...I thought I was good to go .....
The very next day I walk out my door to take my pooch out on his morning walk and I see a large puddle of green under my car in it's parking space ...
anyway to make a long story short ,
this morning we took a look under the hood and it turns out my water pump went w out any prior warning ......
I'm actually starting to think this car is haunted by a ghost named Murphy ....
There is good news to this whole story .
I decided to give my car a "fitting name" that reflects the exact nature of our 5 year long journey together ...
I decided to name my car What's Next ? ...
You know , I'm actually surprised at how fast I came up this name for my car ....and I'm also gonna fix the water pump ...
Then when I get done with What's Next ? I hope to be in a position to upgrade my version of SONAR to the latest version ..
all the best ,
Kenny
