If you want to do it, go for it. I don't see that it's a big deal to try it if you have the hardware and $$$.

You are really asking for information that no one has...not many people run more than 1 character, let alone 10. If YOU think you can handle it, that's all you need IMO. Otherwise, you will just get a lot of baseless opinions -> the one boxers think the dual boxers are nuts who think the 5 boxers are nuts who think the 10 boxers are nuts who think the 25 boxers are totally samwise insane.

So, just be part of the experiment.

Have fun! Let us know how you do.
