You will probably gain a little bit more free ram. I bet your total usable ram is < 3 gig and moving to x64 will most likely allow you to use your full 3 gig that is installed. And in fact if you wanted to add some ram you could then do that whereas you cannot get any more free ram with x32 in that machine with that 1 gig graphics card.

I can only use less than 2 GB of ram because 1279 MB are shared with the grapics card!!

can i set less shared memory?

2303 MB for grapics are really too much for my pc...

Well the graphics card would start at 4 gig and move downward. So it should look like this:

|---------------------- 3 Gig Ram ----------------------| 1 Gig empty |
------------------------------------------------------------------------------------
|------------------ Windows/programs -------| 1279 Video Ram |

So really you should be losing just 300 meg of your 3 gig for the video card and a little more for other hardware. Leaving a total of 2600MB for windows or so I would guess.

With windows x64 and a compatible motherboard it would look more like this:

|---------------------- 3 Gig Ram ----------------------|---------------------------- 61 Gig empty --------------------------|
--------------------------------------------------------------------------------------------------------------------------------------------
|------------------ Windows/programs --------------|................................................| 1279 Video Ram |

Leaving your full 3 gig usable and allowing space for you to upgrade to 4, 8, 12, 16 or ???
