I know desktops inside and out, but I am curious about some of the newer gaming laptops and their strange video cards.

Right now I have 2 desktops, an i7 with 6gb ram and gtx280, and a q6600 with 4gb ram and gtx280. I am going to part with the q6600 and pick up a laptop, but I don't know how the video cards compare.

I have found a couple different ones and would like to compare them to what I see currently, but can't find good comparrisons. I see the GT540, GT335, GT340, GT260m and GT260m SLI.

Can anyone tell me how any of those will perform against my GTX280? Currently I'm getting 60fps in the wild at mid-high settings, 40fps in town. Will I be able to enjoy the same quality video with these other cards?
