The bit specification on your graphics card is talking strictly about the width of the vRAM's bus. For example my GPU utilizes 192-bit vRAM interface.

As far as Windows is concerned, the operating system will be either 32-bit or 64-bit. This specification is separate from what kind of memory interface your GPU is using. If you have 32 bit flavor of Windows installed, it will always be 32 bit, unless you install a 64-bit version.

To answer your question, your system will not become "64-bit" because your GPU's own memory operates in a lane 64 bits wide.
 
also good thing to bear in mind is that lga 775 socket is old enough that there are only AGP and PCI slots, no pci-express that all recent graphics cards use.

So whatever you do, do NOT buy pci-e card for that computer, you cannot get it to work with it.

Last AGP card on market that I could quickly find was ATI/AMD HD 3450 which was DDR2, meaning that most likely any card with DDR3 memory would be PCI-express and so no compatible.
 


That's not true. I have a LGA 775 MSI P35 Platinum Combo mobo at home that has PCIe x8, x4, and x1

Manan, can you give us the make and model of the motherboard you are using?
