Just bought a T510 with i5-540M

I just bought a Thinkpad T510 with an i5-540m. It was only 35 bucks and it should be here later this week. Don't know if I should have, but I'm an addict now. Anyway, would upgrading to an i7-640M be worth spending 30 dollars on. I have no idea what the screen resolution is and it's running 4 gig ram. I also has no battery, but I want a 9 cell for my T430 and the battery out of it should fit.
What do you all think.

In my individual opinion the Pro of this is cyrenaicism, the Con is you are poorer $30, thermal paste, and 30 minutes.

The i7 640M won't even give you 200MHz more than the 540M. Definitely not worth 30 bucks.

To be honest, I can't understand settling for a first gen Core i5/i7 when objectively better ones can be had.

I mean, if you get a T530 you can upgrade it to a quad-core, which you can't do on a T510. Plus the better integrated graphics and USB 3.0.
