UMA Shared Memory

I have a Sony Vaio laptop that is about a year old. My video memory is shared with my RAM When entering the BIOS I can change the video memory from 32MB to 128MB. I've just recently max out my memory to a 1gig. When I change my video memory from 64MB to 128MB I don't notice any change when playing games. Why is this? Here are further specs of my laptop:
Video name: ATI Radeon IGP 345M Chip type: RS200M AGP (0x4337) DAC Type: Internal DAC (400MHz) Page file: 327MB used, 1849MB available DirectX Version: DirectX 9.0c

Summary: No, if you install a 64 meg AGP card, you will have 64 Meg of video memory, which will be more than enough to run The Sims 2. You will notice that the 32 meg "shared" memory your on-board video was us...
