Trying to justify $$ for new i7-720QM CPU on Laptop.

Greetings,
recently purchased a Dell Inspiron N7010 that I am really quite pleased with. It has a build date of Dec 2010 but was never turned on until it came into my possession.

A little research & I found that this machine will support i3, i5 & i7 processors. Currently installed a Core i3-370m which only supports Memory type DDR3 800/1066 MHz. I had some extra RAM & installed 8GB of 1333 MHz.

Alibaba.com (?? anyone ever heard of Alibaba ??) has Core i7-720QM's for $111. I believe the 720QM is the least expensive of the first gen quadcore's & it will support RAM @ 1333MHZ. Was considering a SSD anyway. The SSD & new CPU will cost as much as the laptop. Would the increase in performance be worth cost?

Better suggestions appreciated.

Or - I should probably just be happy with a good deal & enjoy.

thanks

Just noticed that the i3-370M has "Integrated Graphics" which the i7-720QM does not. This machine also has "Intel HD Graphics". i3-370m came out a year later that the i7-720QM & so you would expect some improvements.

I wonder if this graphics display is related to the Core i3 supported "Integrated Graphics"? Possible multiple monitor too.

Yes, thanks. More research is needed for sure.
