Yet care must be taken in regards to memory on the graphics card.
Some of the cards have 2 GPUs on them, and the memory they have is split between the 2.

Take the NVidia GeForce 9800 GX2 for example.

It is offered with 1 GB of memory. Yet, since it has 2 GPUs, the memory is split evenly between the 2 GPUs, resulting in what is basically a SLI-configuration of two 512MB cards.
And I don't know if Vue supports SLI... ^_^"

So, to sum it up, don't just look at the amount of memory, also make sure it is actually a single-GPU card.
