"Because the Lenovo says, "shared system memory." So, to me, that says that
it will take whatever it needs from the 1GB or 2GB of memory I have."
That is probably what it means, but I'm not sure about this.
"I am unsure if 256MB plus the 64MB onboard will be enough to do decent 3D."
All other factors notwithstanding, it probably would be. But as I said
before, the amount of RAM is not nearly as important for performance as other
factors. One of these factors is the ''type'' of RAM.
DDR3 RAM is ''much'' faster than DDR2, for example.
