But here's the deal. You won't get enough boost to really feel it. This won't get it playing video games any better.
I own a similar C2D Sony and the best upgrade for it was to put in a SSD.
I am thinking about upgrading the processor of my all-in-one (which is an Intel E7500 Core 2 Duo, chipset Intel P43 Express)
to an E8500 which (according to compatibility lists) is supposed to be compatible with the the chipset fitted
Can anybody comment on whether this would be ok?
