Thats because the system which shows 1790 has 256MB shared video memory used by the integrated graphics card. You can decrease the shared memory from BIOS, which i don't recommend if casual games are played in that system. You will be having a graphics card installed which has its own memory, so there is no need to share memory from the Physical RAM.And 64bit OS requires more memory as the CPU executes instruction sets of 64bits in size. That's the reason the minimum memory requirements are more as compared to 32bit OSes.
