A 64-bit machine is capable of processing twice as much data as a 32-bit machine.
The Nvidia Q600 is a powerful graphics card. Suited for both 32-bit and 64-bit Windows computers, the card is capable of handling high-speed games and other software requiring speedy graphic renderings.
The main difference between 32-bit and 64-bit systems is the ability to simultaneously manage multiple processes. The 64-bit Windows machine is capable of processing twice as much data as a 32-bit machine. The 64-bit system therefore takes full advantage of the powerful Q600 card.
A 32-bit machine is limited to utilizing less than 4 gigabytes of random access memory (RAM). The 64-bit machine has no RAM limitations, making it a better choice for more-powerful computer applications, such as video editing and gaming.
The 32-bit Windows computer has been the standard for years, and software vendors have built their software to work with it. Software designed for 32-bit machines will run on 64-bit machines, but 64-bit software will not operate on 32-bit machines.
