Yes, also i386 will make better use of cache on the cpu which means some software will be faster. However amd64 provides a larger virtual address space which has security benefits (better ASLR). It also has more registers which means other software will be faster. > Of course, if RAM would be added you would regret not having installed > amd64... Yes to this too. It is a trade-off.
