Improvement from P-M 1.73 to 2.0?

As the title says how much of an improvement would I see going up to 2gHz? I'm talking about in games here-I don't care if it makes windows faster honestly (well a little faster startup would be fun).
The other question is would there be a noticeable difference from 2.0 to 2.13?
I have options because I am planning on springing for a old 400mHz FSB on ebay and pinmoding it (there no way I could afford a new one at the actual clock).
Just wondering because I'm willing to try my hand at the pinmod and it seems like a cheap way for a decent upgrade (despite the risk, I'm a cautious person) if the answer to the original question is in the right direction.

 

You will not see a significant difference going from a Pentium M 740 to a 760, don't bother. The bottleneck in your laptop is the video card, so perhaps you could look into overclocking it if you want some extra performance.

Nope. I'm not sure if a pinmodded Pentium M would be stable over 2.00GHz. We had an article on pinmodding here:

Thanks Chaz that article is the place where I got the idea in the first place. The interesting thing is that I had thought the same thing and was all set to tweak my GPU clocks a bit today when I realized that the utility in nvidia's control panel wouldn't let me. When I change anything either the memory or core and click the test these settings thing it says that it wouldn't work and I had to lower it and try again. It says I'm running at 375/1200 (I would assume the mem is the combined of all the memory modules because thats defiantly too high) Kinda goes off topic with this thread but yea....
