I want to have a Nord sound . help Any comment

[koessounds]

Hello Guys.
First of all, I apologize for poor englinsh skills, It is not my 1st language

Anyway,
I look forward to using nord sound. My major genre is hiphop/soul. So I do not sound making extremly.
I used to using sound source which is attract my first feeling instantly. and then, did a sound making a little at post stage (Mixing)

I have yamaha synth, which is not expensive but useful, not bad sound, used to using it sub sound source not a main source.

Due to rack of space / budge, I looking forward to buying Nord Rack version.
After information search, Actually Rack version is now, old equipment, Clavia seemed to don't release newer equipment.

I find out rack version of nord are Lead2x/4, Electro 2, And Nord Rack3 (I think it is lead3 version)

In this point, I have a question.
I proper more realistic sound, don't like much synth sound. I will using it mainly piano/EP/Organ/Pad sounds.
I think Electro 2 Rack version is most appropiriate to me, But have a worry about Very old version.
I heard that When I want to change the sound or os update, I must using 32 bit computer

what equipment do I buy? actually, Keyboard version of stage 3 or electro 5/6 will be perfect but I do not have a room both space and budget

Any Helpful Comments are appreciated.
Thank you & Best Regards

I {prefer} more realistic sound, don't like much synth sound. I will using it mainly piano/EP/Organ/Pad sounds.

The Electro 2 rack is the only Nord rack with piano, EP, and organ sounds (and the piano is not so good). It does not have pad sounds. It sounds like you'll need some other unit instead of (or in addition to) the Nord.
