Hi Noticed the other day that my Windows is 32bit, but my processor is a 64bit. Which means that i can upgrade from 3gb ddr2 so-dimm ram to 8gb if I upgrade my windows Processor Intel Core 2 Duo P8400 2,26 GHz Graphic GeForce 9600M GT 512mb So my question is: Is it worth to add more memory too make KSP work better for me?
