Is my computer compatible with a AGP 64MB Video Card?

More specifically, I'm looking at a XGI Volari V3 64MB DDR AGP Video Card w/DVI TV-Out. I have a PCG-GRT100P Sony Vaio laptop with 32MB video memory. I need to upgrade slightly to 64MB. Will this do the trick?|||That is a desktop graphics card, it will not work with a laptop.
