...and what does a 1.8 triple core equal out to be? Would that be equal to a 5.4 or does it calculate different?

It depends, if the game only uses 2 cores, then your 1.8Ghz quad/Tri-core becomes a 1.8Ghz Dual.

What games is it? A game will install regardless what CPU you have though, it just wont run well if anything.

You need to tell us what game you are talking about and link us there. GHz do not matter as, for example, a sempron 2.7GHz is massively faster than a pentium 4 3.4GHz.


It calculates differently.

EG, Athlon IIx4 620. You basically have 4 CPUs at 2.6GHz each. A program can run on one core. It will have available 2.6GHz of processing power. You also have a large amount of non-intensive background programs running that each can use one core.
Now you have say, a game called Dragon Age Origins. This program has been written so that it can run parts of itself in parallel. Each part will have 2.6GHz of processing power. But the program will run faster because it has split its workload among 4 CPU cores.
Most games today can use 3 cores. Older games can use 1 or 2 cores. A few games like FSX, GTA4 and DAO can use 4+ cores.

Metaphor:
Jimmy wants a sandwich. Frank says he'll make it. Jon wants to help but he can't because making a sandwich is a one person job.
Jimmy and Fred each want a sandwich. Now Jon can help. Two sandwiches can be made in the time of one because Jon and Frank are working in parallel, each making one sandwich.
Jimmy wants a sandwhich but wants it cut in half. Jon has an idea. Jon and frank go into the kitchen and frank cuts a piece of bread in half. Now each make half a sandwich with reduced time vs one making the full sandwich then cutting it in half.
