Video card taking 1.7GB of system RAM. Please help.

I recently built a new computer with Vista Home Premium 64bit. I went to run the Vista Experience score index and my show details showed me something quite odd.

It seems as if my video card is taking 1.7GB of my system RAM, how can I get it to stop? (I want to hit a 5.9 in RAM score but I believe it won't as long as my video card is taking that much RAM from the system RAM).

A single GTX does not need 2.5GB of Video RAM, that's absurd. Please, this isn't a stupid bragging topic or anything (I asked on another site and got some pretty immature responses because they all thought it was a bragging topic since I had a 5.9 in my shot...ewww scary, they failed to see that there was a problem.) Several of the people on the EVGA forums were more interested in the fact that SupCom was crashing with 4GB of RAM, and the issue of a GTX with 2.5GB of VRAM was tossed out the window. My RAM is running at 4-4-4-12 timings 2.2V not overclocked just at retailer suggested settings. I know several people that have 2GB of the same RAM and are getting 5.9s with the same RAM and OS as I have.

Weird looks like it has turbocache enabled??
