You may want to try and do some additional optimization, even once you get the turbo (a cooler CPU is a happier CPU)! I recently put together a spreadsheet that gives values for each preset and what CPU % they use which, in conjunction with some other optimization, saved me ~20% for my kitchen sink preset. The biggest factors were:
1. When a block is bypassed, make sure it is set to a value/type/channel that has low CPU % (this was about 12% of the 20% I saved).
2. The other big % saver was reducing the IR Length on the cab. That saved me 5-6%. I will still use full IR length for recording, but for live play, not necessary IMO!
Here is a link to that spreadsheet:
Axe FXIII CPU Usage per Block
This spreadsheet was built around FW19.07, and I will be creating a new one adjusting blocks affected by FW20.0, but it is still a good road map to help find places you can shave some %'s! PM me if you have any questions and congrats on the Turbo order!
