Currently have an Intel 845WN 478 socket with a P4 1.7GHz.

What is the max I can put on the board, will I notice a great deal of difference and is the 478 pin important.

Machine has 2 256Mb

Sorry for what seems a bunch of idiot questions but any help appreciated.

Cheers

Nick

look at your m/b manual or find it on the Intel website it'll tell you there.

Yes Socket 478 is the importmant bit, you can only upgrade with 478pin CPUs. M/Bs are grouped as Socket A, 478, 939 etc so only a 478pin CPU with a 478 M/B

May need to check your BIOS revision also before upgrading:

Thanks for the BIOS advice have undated this.

Have searched for a 2.6 CPU and there appears to only be 2 on ebay none via PriceRunner or DealTime. Would I be better to change the Motherboard so I have a wider selection of CPU. Would this have any knockon effect regards the rest of my system having to be updated.

probably is best from the type m/b, all depends on what you want it for, its all to easy too get sucked into the latest stuff - its an endless cycle of upgrading. theres a number you can choose from on ebuyer/dabs

If you do change your m/b, youll need to change at least your graphics card & ram

Thanks for the advice, looks like I could get sucked down a dark hole

If you change your motherboard then you will need to do a fresh install of windows XP. It gets fussy when you change that component. It all depends what you want to do with the PC. You may be a little limited to playing top of the range games. By maxing both the CPU and RAM you should notice a bit of a speed increase.
