Asus External Graphics Card
Now you can upgrade the graphics on any laptop with an express card slot.
I've tried the demo...
It runs alright but to make it so the animation wasn't too choppy I had to turn the settings WAY down. Still was very playable however...download the demo and give it a try; mess with the settings and see what...
I'm sorry, but isn't the M70 different then the e1505? I don't think it'll work. Your best bet of upgrading to better video card in the e1505 is to wait for Dell to start installing the x1450 in this model. Definitely need a BIOS...
