I have a Latitude D830 with a T7300 @ 2.00 GHz processor which I'm looking to upgrade to the T7800 2.6 GHz processor. My question is, are there any risks involved in upgrading a processor in terms of other hardware installed. I've upgraded to 4 GB RAM and the system comes with an NVidia Quadro NVS 135M video card. Is it even worth upgrading the cpu? I'm planning on buying a new computer but not for another 6 months or so and I'd like a little more power from my cpu until then...
