it's just windows xp for 64-bit processors
if you don't know what it is or whether it will improve your computing experience, it's not for you

from wikipedia

The primary benefit of moving to 64-bit [from standard Windows XP] is the increase in the maximum allocatable system memory (RAM). Windows XP 32-bit is limited to a total of 4 GB, which is equally divided between Kernel and application usage. Windows XP x64 can support much more memory; although the theoretical memory limit a 64-bit computer can address is about 18 exabytes (18 billion gigabytes), Windows XP x64 is currently limited to 128 GB (237 bytes) of physical memory and 16 TB (244 bytes) of virtual memory.
