PC gaming system requirement help please?

I've just got a new laptop and want some games for it.

I'm looking on Ebay etc for some ones form a year or two ago and saw Assasin's Creed.

I've seen the system requirements are 2.2 ghz or better.

My laptop has a T3000 1.8 ghz.

Thing is Assasin's Creed 2 seems only to require 1.8 ghz.

Does this mean that older games need a faster PC or are new PCs faster by comparisondue to efficiency or something ?
It has 4GB memory so it's good enough in other respects.

Any help most appreciated , thanks.
