What are my limitations?

[Need_a_Dell]

I have a Dell 4th gen XPS system running a Pentium 4 650 3.4Ghz CPU.
I recently went onto tigerdirect.ca to purchase a new CPU, and picked out the Intel Core 2 Duo E6750. This has a bus speed of 1333Mhz, which I just read may not be compatible with my current mobo even though it's an LGA775 socket.
Did I buy the wrong CPU? Can anyone tell me what the best compatible dual-core CPU would be for this system?

What is the model number of the Intel motherboard that you want to put the new CPU into?

 

[Need_a_Dell]

this particular Pentium 4 650 does sport HT technology and the 2mb cache with 800Mhz FSB.
i dont know what the mobo model number is at the moment... but when i get home i'll post it.
am i simply limited by the FSB speed? i'll probably have to flash a new bios onto the mobo won't I?

your motherboard architecture determines the CPU you can use, not just the SOCKET of the cpu holder.

ah, now that's what i was missing, if i find out my mobo model, will you guys be able to help me find out what kind of CPU i can get??
