Well if you must load many samples then you will need the most amount of memory possible. Gigastudio only runs on a PC, and does not support 64-bits yet, which means the max memory you can use for giga is around 1.5 gigs, even if you have 64 bit windows and eight gigs of ram installed. However, you will get faster clock CPU clock speeds with a PC which almost makes up for ram factor.
The new latest and greatest dual 2.7 g5 with Logic Pro 7 (and hence exs), both of which are 64-bit, can address up to 8 gigs of memory silmultaneously. This is an advantage because samples love lots of memory. However, it is debatable whether this approach is necessraily 'better' than a PC.
So it all comes down to which platform, i.e. Mac or PC, you are comfortable with. Either way, max out the ram and use a RAID 0 array to store your samples on.
