Giving graphics care more ram

Hello.

I was told it's possible to make your graphics card lend ram from your system ram.

I have the geforce 6600 gt 128 mb ram. I want it to have atleast 256. I have 3 gigs of system ram.

Is this possible?

your graphics card is a "discrete" card, which means it has its own memory bus, memory, etc.

you can only share memory between the lower end "integrated" graphics cards.

if your video memory is an issue, there are alot of budget cards today that come with 512mb of video ram standard, you can get many of them for under $50, like the 8600GT, or the ATI 4630....
