Question about integrated/non integrated cards

[stabito]

my computer here originally came with some integrated graphics card NVIDIA GeForce 6150SE and i put in a ati radeon hd 4670. now i recently heard there was a way to select the amount of shared memory to be used for gaming or whatever my question is if i reenabled the the nividia card and upped the video ram to like 256(theres 700 something on there) would it add to the 512 that i get from my other card and if it does would it cause more power to be used from the psu

The use of shared memory (for ATI it called HyperMemory, for NVidia it's called TurboCache) is limited to on-board (integrated) chipsets and some budget class graphic cards. Your HD 4670 will not utilize your integrated chipset's ability to use TurboCache memory.
