The VRAM in the new Mac Pro can be up to 6GB. The largest venue for IRs in MIR Pro is 1.32GB.
well, besides you would need at least some memory for the display(s) 😉 it is not as simple.
you also have to get the sample data (preload buffer) into RAM to have something to calculate on and not all GPU processing threads can access all memory, especially not simultaneously.
get an idea reading this article(s).
GPU processing is great for calculations which can be easily fragmented into little portions of jobs, it is not as efficient for multi impulse response reverbiation when the *whole room* is applied to every single instrument.
and remember: only a CRAY can run an endless loop in just three seconds.
