Which of these processors is the best for a medium-high usage laptop?

I'm roughly speaking to buy a laptop and I want to get a justifiably good one and draw from more bang for my buck. Is it worth spending more on one of the dual cores? If so on which one? Or should I stick near one low end CPU and loaf if I need to upgrade?

Mobile AMD Sempron 3500+ (1.80GHz/512KB)

AMD Turion 64 Mobile MK-36 (2.0GHz/512KB)

AMD Turion 64 Dual-Core TL-50 (1.6GHz/512KB)

Intel Celeron M 440 (1.86GHz/1MB L2 Cache)

Intel Pentium Dual core T2080 (1.73GHz/1MB)

Thanks

Laptops are not cheap to upgrade processors, I would suggest you attain the processor that is the fastest right presently and upgrade other things like run into and hard drive after that.





The Core 2 Duo processor is the best right now for power consumption vs processing power. Which is exceedingly important next to laptops.
Intel Pentium Dual core T2080 (1.73GHz/1MB)

Fastest by far. AMD Turion 6f4 dual core isn't bad but will be slower and hotter next to shorter battery energy. The others slow!
