I am using Celeron/Atom CPUs atm and figured a needed a higher performing CPU. I don't want the CPU to be too modern because I don't want the CPU to end up with an integrated government GPS trigger. I thought of the i7 but it is too new, how good is the performance on the i5? I have used a core2due and performance is poor. My current CPU is around 1-2GHz and I can't remember the clock frequency on the core2duo.
