Specs: Windows 7
I am getting a new computer with 16GB's of Ram. I'll have a 1GB video card. But i'm wonder if allocating maybe 3GB's of Ram to video memory would it super upgrade my video?

"1GB video card" which one?
1gb or more of video memory helps when playing game using high settings plus high resolution. To be able to use system ram as video memory the v-card must support hyper memory for ATi or turbo cache for nVidia(most low end v-cards support this technology).

Even if you could allocate some of the system RAM, it would NOT "super upgrade" the video. For one thing, system RAM is generally much slower than graphics RAM. For another, you wouldn't be changing the graphics processor, so the performance will be no better.

Windows already uses system memory for "virtual VRAM." Just as Windows uses the page file on your hard disk as fake RAM when you run out of the real stuff, the shared graphics memory is used as fake VRAM when you run out of dedicated memory on your graphics card.

You can take a look at how much RAM Windows shares with the graphics card under Video Adapter Properties. Haven't checked in a while, but I believe it's around 1.5GB on my main system.

If you're after better performance, you'll need a new card.

I agree that one may be able to run some ram as video ram and depending on the use it may help.

It also may help more if the ram were used a a ramdisk. Load some application on it to run from.

Most video cards are quite special and the way they use ram is or may be much better than system ram. GDDR5 ram is pretty quick.
