Hi.I don't know much about computers but I have a question. I have a Toshiba laptop computer and I just bought Adobe PHotoshop CS5 and it says I need to have an Intel Pentium 4 processor and I have an Intel Celeron processor 900 2.2 ghz. Can I upgrade a processor or do I have to buy a new computer to put that on?>
I would recommend contacting the software developer and asking them if this software will run on your system with an Intel(R) Celeron(R) processor, if they say that you most use at least an Intel(R) Pentium(R) 4 processor, then I would suggest contacting Toshiba* to see what processors you can upgrade your system to.
Keep in mind that the compatibility between the processors and the laptop systems is determined by the laptop manufacturer, not by the processor manufacturer.
