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)

Dell 2.70GHz 800MHz FSB 2MB L2 Cache Intel Pentium E5400 Dual Core Processor Upgrade Mfr P/N 224-5954 $49.55 $42.12. General Information. The CPU you are ordering, if it is designated as OEM it may be NEW or PreOwned. Pentium Dual-Core E5400 2.70 GHz compatibility, 05:46 PM So, I am buying a treat to myself this christmas: A a VGA ZOTAC GeForce GTX 650 1GB DDR5 128 bits PCI-e.
This is the list of processors that I am interested in:
- Intel Core 2 Duo - T9300 - (6M Cache, 2.50 GHz, 800 MHz FSB)
- Intel Core 2 Duo - T9500 - (6M Cache, 2.60 GHz, 800 MHz FSB)
My Questions are:
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?
Is the BIOS (Version A13) going to recognize the new processor?
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?
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.

You would have to look into the specifications of the motherboard of your laptop. If you look at specs of the CPU you currently have, it seems it's available as BGA and PGA.
BGA refers to Ball Grid Array and usually means that the CPU is soldered to the board. In that case you would not able to replace the CPU.
You would have to check your manual on whatever CPUs would be supported, assuming you can replace them. By taking a picture you could also let people help identify it, after all you said it's information from the CPU so I guess you opened the laptop. Generally I would expect there to be some kind of screw or similar to loosen the CPU if it was removable. If there is nothing like that in place you probably will not able to replace it.
Lets have a look at the specs of the CPU and what sockets they support:
- Intel® Core™2 Duo Processor T7250: PBGA479, PPGA478
- Intel® Core™2 Duo Processor T9300: BGA479, PGA478
- Intel® Core™2 Duo Processor T9500: BGA479, PGA478, PPGA478
It should be save if you have the same number as it would be the same socket. So at least the T9500 should be a fit - if you get the right version.
As for whenever it's a good upgrade it depends on the kind of work you do. You told us which applications you're using but didn't say aynthing about the actual work. Depending on it a faster GPU would be more of an upgrade (unlikely that's replaceable).
Oh and consider including information from responses you might get on your CNET post.
