Summary: I have always been an AMD fan, and when I was looking for a new laptop to replace my Sony Vaio Pentium 4, I sought out an AMD platform. I really liked the new HP Pavilion (this was 2007) laptops, so I picked up the Dv6458se (special edition Dv6500) with the AMD Turion X2 TL-60 CPU over the Intel Core 2 Duo because it was AMD and was about $150 cheaper for the same spec. I was really happy I did! The Turion line is AMD's lineup of mobile CPU's for laptops.
Summary: Considering the performance of the TF20 single core CPU that was in the machine this has been a tremendous performance upgrade. We gave our old acer 5532 laptop to our children, but it would freeze and jerk while they were playing flash games on nick jr. We have not had any problems with the TL 60. I took my time during disassembly, cleaned the old heat sink very well, used new thermal grease, and put it back together.
