just wondering and how much will this increase the performance.
A decade. Give or take. It'll be a little while yet before we really see realistic gains from 64bit software.
/me wonders how many one line first post threads 0111101001101001_OC is going to make.

Oh yeah... 128 bit CPUs probably will be out in like 10-15 years. each processor bus width seems to last about 8 years, though 32 bit lasted a LONG time due to dual ALUs in the pentium family so the data bus was actually 64 bits but registers were only 32 bits - I predict that dual and quad core CPUs will extend the lifetime of 64 bit systems in a similar manner.
