I have been looking at the 7300GS specs on the nvidia website and see that it has tubocache. Is turbocache similar to AGP aperture size (I read somewhere that this is the amount of system memory (RAM) shared with an AGP graphics card in order for it to have more memory to process textures and other visual data). If turbocache works in the sameway can you set the amount of system memory that it uses? For example could I buy another 256mb of RAM and tell it to use only 256mb of memory? I see that the 7300GS supports upto 512mb of memory but most of the 7300GS say 'needs 1GB of system memory', how much do they use, will they really slow the system down?

Nvidia 7300GS and the mystery of turbocache.....

They come in either 128MB or 256MB, and will use Turbo cache for when textures dont fit on the onboard memory.
In a 512MB system, the 128MB card will use 128MB of system memory to give a virtual 256MB frame buffer. If your system has 1GB of memory, the 256MB 7300 GS will use another 256MB to seamlessly present games with a 512MB frame buffer.
This isnt a gaming card, its main selling points are that it decodes H.264, MPEG2 HD stuff, so its aimed at HTPC's mostly.
