32nm vs 45nm

[evadin]

Hi there
I'm going to buy new motherboard for my i7 2600k and i'm wondering is it ok to go with asus p8z68 v when it says it's 45nm. "LE" version of this motherboard is 32nm just like my cpu architecture, but does it relly matters?

This Asus motherboard support your CPU, and will OC well on it
