Upgrading Processor - Dell Latitude e5400

Hello everyone! My laptop is Dell Latitude E5400. Recently, I replaced the old 240gb/5400rpm hard drive with a Kingston 240gb SSD. I also added 2gb/800mhz more RAM and now it has 4gb in total. So, I decided to replace the processor (Intel Core 2 Duo T7250/2mb L2 cache) with a faster one. (These are the numbers on the top of the processor if they help: LF80537, V947A355, SLA49)

This is the list of processors that I am interested in:

1. Intel Core 2 Duo - T9300 - (6M Cache, 2.50 GHz, 800 MHz FSB)
2. Intel Core 2 Duo - T9500 - (6M Cache, 2.60 GHz, 800 MHz FSB)

My Questions are:

1. Will it work? I am really confused. Can somebody explain the difference between BGA479, PGA478, PPGA478 sockets? Are these T9300 and T9500 processors compatible with my motherboard socket?
2. Is the BIOS (Version A13) going to recognize the new processor?
3. Do I need to change my 65W power cable with bigger one if the new processor is with the same 35W consumption as the T7250?
4. Is the upgrade worth it? I am using the laptop only for small graphic design works with Corel Draw, Adobe Illustrator and Adobe Photoshop. Is there going to be a significant improvement in the performance?

*Note: I am not interested in buying new computer.

Thank you very much for the help and the information!

Re: upgrading processor

If you can't find the processor compatibilty list for your laptop on the Dell site (even after providing the service tag), ask their customer support. Such a list should tell about the necessary BIOS version also.

If Dell says it can be done, see if you can find benchmarks to compare the current CPU and the ones you want to replace it with and then decide if it's worth the money for you.

Too small a gain in my view. Have you upgraded .....

I have a core2duo laptop. Some 2009 Vaio and it's on the list to get a move to SSD. Overall you'll gain more from a move to SSD and maxing out the RAM.
