    I'm not sure if this is in the right place... But on the $1349 (Canadian) iMac, the ATI X1600 comes with 128mb of SDRAM, while on the $1699 model, the ATI X1600 comes with 128mb of VRAM. So, does this dfference effect gameplay while playing games like WoW? Also if it does... how much of a difference?

    Thanks

    Are all the other specs the same? It appears both computers have the same amount of video ram.

    SDRAM is just a type of memory. VRAM is a short term for Video RAM which is a generic term for dedicated graphics memory (these days). iMacs that have dedicated Video RAM currently use GDDR3 SDRAM for their VRAM.

    I think there is a type in the original post and the second amount should be 256Mb not 128Mb, in which as the question is do you notice the difference in the amounts of RAM. The answer to this is game specific, but in general yes: the additional RAM will allow higher resolutions to be playable at a decent frame rate as textures will have to be paged in and out of VRAM less and there will be more space for the frame buffer.
