Here are some info about the benefits for LGA775 CPU (pinless)
- No more problem for broken pins on CPU.
- The cpu was made of a denser array of gold contact points which makes the cpu more durable, and allowing connector density to increase without radically enlarging the size of the die.
- Improvements in heat dissipation. LGA775 cpu have better heat dissipation properties.
- The LGA775 cpus offer a clock frequency higher than the PGA.
All the best,
