Could my system run with x64?

I would like to upgrade to a x64 system but i am unsure if all of my hardware is compatible. Any help would be appreciated.

I'd be surprised if you couldn't. Look at the following link regarding your CPU:

How do I tell if my computer can run a 64-bit version of Windows?

To run a 64-bit version of Windows, your computer must have a 64-bit-capable processor. To find out if your processor is 64-bit-capable in Windows 7 or Windows Vista, do the following:

Open Performance Information and Tools by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type Performance Information and Tools, and then, in the list of results, click Performance Information and Tools.

Do one of the following:

In Windows 7, click View and print detailed performance and system information.

In Windows Vista, click View and print details.

In the System section, you can see what type of operating system you're currently running under System type, and whether or not you can run a 64-bit version of Windows under 64-bit capable. (If your computer is already running a 64-bit version of Windows, you won't see the 64-bit capable listing.)

Look up your i7 950 cpu at Intel -

ARK | Intel® Coreâ

and it says Instruction set 64 bit, so with the 6GB RAM you're good to go.
