I didn't upgrade this year and future upgrades are uncertain.
I've pretty much given up on using VSTi's with BiaB/RB beyond the included "Coyote", or Sample Tank, because of consistent crashes and sluggish performance.
I can load 8-10 VSTi's in my 64-bit DAWs with no problem. BiaB can hardly handle 1.
My only use for BiaB at this point is to generate a midi file I can tweak in my 64-bit DAWs using High Quality VSTi's.
Real Tracks are occasionally useful, but the new generation of VSTi's sound better, IMHO.
