I know the reviews in THG used the ati radeon 7500 with 64 MB (or is it 128MB?). The laptop I'm considering to get is a Dell equipped with ATI RADEON-M 7500 32 MB. Will there be a considerable difference between the two? I am currently using a desktop with a geforce 2 mx 32MB. Would either be a worthwhile upgrade to my current machine?
Yeah I want to get a laptop for gaming because I am rarely if ever home these days.
What games are you looking at playing? If you were thinking of intense 3D first person shooters, it would probably be a much much better idea to go with one of the newer GF4 Go or Radeon 8500 Mobility chips. Those are actually able to game at a respectable rate. I think Anandtech had a review of those two chipsets.
As for your current desktop, it really depends on what CPU you have. If you have a older one like a PIII, most likely one of the newer GF4s or 8500s won't be able to run at full efficiency. Though if you did upgrade, you would still see a significant performance boost since the MXs were bandwidth crippled.

I didn't know there was a Mobility 8500?
Anyway the Mobility 7500 significantly outperforms the GeForce 2 Go, THG has an article in the graphics guide section. The GF 2 Go was essentially a cut down version of the GF 2 MX, so the performance may well be equivalent to what you have now.
There are a few notebooks popping up with GF 4 Go's in them, and as UoMDeacon says they would be better.
