If this holds true i would think i'd have gained 256mb or 512mb of usuaable ram? am i wrong
remember that the ram decreases only as its used. If you run a game that only uses 128MB of ram, you're only losing 128MB of ram. Its realtime, it goes up and down.
There is also no rule that says that the video card has priority - in the example of a 2GB system with a 1GB video card, you could end up with 1GB of usable ram and 1GB used by the card - or you could have 1.9GB of usable ram, and 128MB used on the video card.
