32 Bit 64 Bit

Here’s a question I’m not computer/Cubase smart enough to fihure out.
I have 32 and 64 bit installed on a WIN 7 64 bit machine.
Some recordings are 64 bit…better at Vari Audio for editing.
and if I want to add Real Gtr or Real Start (program) it doesn’t run well on 64 bit.
I need to run in 32 bit also for mixing cause some of the plug ins crash the 64 bit.
'm I losing any quality ? The extra head room is not an issue.
Opinions ? Suggestions?

Thanks
Terry

There is no audio quality difference between 64 bit Cubase and 32 bit Cubase, they both treat audio the same way.

There must be a sticky somewhere on the interwebs for this…
