its neat.. isent it ? ;)

 

Indeed, very neat. I'm very impressed by how much more speed I get. It's by far the best upgrade I gave my D620.

 

I also like to praise the build quality of this laptop. It's always a pleasure to work on. Very easy and fast.

I've made a lot of upgrades on this machine and always loved to work on it. Quality is on par with alu powerbook/macbook pro from Apple.

Things I've upgraded so far:

-1x1GB to 1x1GB RAM and a year later to 2x2GB RAM

-Glossy screen to matte screen

-3 hard disk upgrades

-new wifi card

-CD burner replaced with DVD Dual Layer burner

-new bluetooth card

-new inverter board for the lcd

-new CPU

 

I can recommend the CPU upgrade to everyone witch still has a Core Duo. Also a 7200rpm hard disk makes a big speed difference.

Hmmm <_< Not an option for me right now. I need at least 256GB to let my lightroom+itunes library fit.

Right now that's not really possible money wise although 64GB SSD+500GB HDD would be perfect. But not possible in my D620 :(

I am considering doing this. It is the only other upgrade (with the exception of an SSD, whish is too expensive at the moment) for my D620. My computer has the same stock CPU that the OP did. My question is what is the difference in all of the C2D processors on Ebay. Will any of them work or should I be looking for the T7200 specifically?
