Need Advice on Processor Upgrade

[Luke1995]

Hi, I have a toshiba running Kalyway 10.5.2, and some apps close upexpectedly when the processor is being used lots.

Someone told me this was to do with the processor only being SSE2.

 

I wanted to upgrade the processor from my Pentium M 1.8 GHz S479 to a dual core intel processor, with SSE3.

 

 

Could anyone recommend one?

 

My laptop specs are:

 

1.8GHz Pentium M

1.5GB RAM

64MB Shared Video RAM

 

 

Thanks in advance.
