im a stupid ass

I want to buy a new processor and i dont know what all the shit indicators are ,back in my time only GHZ matters now ;'\
what the fuck is?
64 3000+ /2.0ghz
sp 3300+ /2.0ghz
why this
165 /1.80 ghz cost a shit load of momey more than the others 2?
someone please explain

The 165 /1.80 costs more money because it contains move Level 2 cache than the others. The more L2 cache you have, the better your computer's performance. However, L2 cache is quite expensive, and that is why the other two processors are cheaper
