Best & cheap RAM for this combination?

P.S. I am using a GTX660

Bit over $40.
G.Skill Ares 8GB (2x4GB) 1600Mhz CL9 1.5v. $44

Its low profile, so compatibility with large heat-sinks isn't going to be a problem.

How much would it matter if it was not low profile?

Depends whether you are going to have a large heatsink on your CPU. If your looking at something like a Noctua NH-D14, then there might be issues with the RAm being too tall.

Ill be using the standard cooler which comes with the AMD Phenom. And I can't find that same RAM in the netherlands  .. It was cheap as well  ..

What about those corsair valueselect ones?

And would I notice a difference between 1333 and 1600?

You will see no difference between 1333 and 1600, unless you're running a benchmark.

Get this 1600 memory. It's the highest quality but also among the lowest cost, currently under $16 per 4GB:

While it's not rated the fastest, it's actually made from chips faster than those found in most DIMMs advertised with higher speeds.

Thanks for the link. Hope shipping isn't that expensive  

How are these by the way?

Probably lower quality. Look for something made with chips branded as Samsung, Hynix, or Micron, rather than as G.Skill, Geil, or Corsair.

I don't think they sell those here, or it's very rare.. I'll keep on searching for them. But isn't Kingston any good then? What about 'Dane-Elec'?

G.Skill and Corsair are two of the most respected brands when it comes to memory, their fine. Never even heard of Hyrix and Micron. Geil is more know for their fans I will admit.

EDIT: To prove the point, I got confused between Geil and Gelid.

Basically there is little difference between RAM of the same spec's, get the cheapest or from a brand you trust.

Okay thanks, really enlightened me there!
