Boosting old laptop...

I got an old laptop I am only using for charts, online programs, EFB...It is very slow in general, ASE to open needs a very long time, CPU often at 100%...It's an eMachines E510:Intel Celeron M 5601GB RAMonboard graphicsNew HDD Seagate 250GBThe mainboard supposedly supports T7300, so I was thinking of upgrading.Also wanted to put 4GB RAM in it and a small SSD + Windows 7.Question: is that a worthy upgrade? Am I really going to see much better performance?My problems are with EFB which is using lots of CPU on the movable map, and general responsiveness of the laptop. I couldn't care less about the looks of the laptop, it's size or weight.An alternative is a new laptop 600€, probably Asus, i5 or something.As I have windows 7 laying around here, that is free, SSD is 100€, this is a non-must investment, but a neat one, rest is around 80€ (CPU and RAM), CPU 2nd-hand (ebay), RAM new.Also, if T7300 is working, then T7500 should also work, right? Because I found one T7500 for 40€.What does anyone think?
