5.1 software on a PT's 3 system?

[Seeee]

I just recieved a Project III PCI system. a disk i/o, a dsp card, and an old 888 (16bit).

would I just be better off using my digi001 system? I'll have to buy software for the project system so I am wondering if it'll be worth it. plus the analog i/o on the 888 is only 16 bit. I do have a 24bit spdif converter but I'm thinking it's just gonna be more trouble than it's worth.

I was kinda hoping to just use this tdm system to run beat detective to clean up drum tracks but I guess beat detective is PT's 6 only? and PT's 6 wont run with a project card?

can anyone confirm this or suggest what i should do with this stuff? if it did 32 tracks i'd be Ok but 16 tracks is very limiting.

and can I run another 888 and mix on a console?
