I have run as home studio now for twenty years or so, I am no techy but I do know that I had years and years of using a sequencer that could not behave as it should becuase of hardware limitations, until I got a core i7 920 and ran it in Win 7 64 bit.

Now everything works as its designed to, and nothing is coming up against hard limits.
Maybe te core i5 is also a decent machine,
I know (OK I think I know) that unless an application is written for four cores then it does not use them, maybe just uses a sigle core, or at best uses the cores in a limited way (not sure).
If you run in 32 bit there is no sense in fitting over 2 gig as the operating system can't access it and so it is dead. Ther is a woraround - some sort of soft switch, but tghat only accesses a little more. I think win 32 uses about 1.2 gig of the 2 gig available and there rest is there for use by apps.
