Hello Pedro,
[I've split your post off to this new topic.]
If you enable both the 'high definition pitch shifting' and 96 kHz options in v6, then very, very roughly you're likely to need at least 4x as much computing power available as v5 would need for any given organ.
Whilst I'll probably need to leave other people to comment in more detail (if they have any thoughts on it), I see that the CPU model you mention has 22 physical cores, with a clock speed of 2.40 GHz, supports AVX2, 2.5 MB CPU cache per core, and was released in 2016:

Whilst more-recent models are likely to be more powerful (all else being equal), multiplying the number of cores by the base frequency gives 22 x 2.40 = 52.8, which could be used to give a very, very rough benchmark to compare against your existing CPU for polyphony capability. (However, there are also overheads in synchronising additional cores, so polyphony won't quite scale linearly.)
Note also that the base clock speed is still very important (even when there are very large numbers of cores), for things like processing background models, organ loading speeds, processing MIDI events, etc.
Hope that's of at least some help!
