A newbie to the mobile world so excuse what may seem an obvious one to start.
I have an old Viao FX505 with a Mobile AMD Athlon 4 running at 1.2GHz and of course in the great scheme of things I started wondering what would be the fastest AMD CPU that I could replace it with.
Everything else I have the specs for , the DVD/CD-RW, the HDD and am quite happy I can do those, but the CPU has me foxed.
