preferably from someone who OWNS an NVIDIA.....LOL
I've had many Nvidia cards in the past Geforce4 Ti 4200, Geforce 8600 GTS, Geforce 9600M GT to name a few. A GT240 performs similarly to a Geforce 9600 GT, which isn't capable of utilizing 1Gb of video memory.
1GB of video memory is of benefit to only high end gpus that can play games at high details and resolutions, typically it makes a difference at 1920x1080 and up especially with antialiasing added. BUT mid range and low end cards are so weak that they can't make it to that high of a resolution anyway, they start getting low framerates at lower resolutions and detail levels because of the strength of the gpu itself, by the time they get to the point of seeing the would be benefit from the 1Gb of memory they've already reached their own limits.
