I have a friend who is willing to purchase my CPU (E8400 E0 Stepping) for $125. Should I sell it to him and purchase a Q9550 from Microcenter for $169 or just keep it? The processor is a little over a month old and has great temps and overclocking ability.

If you overclock, then it depends on your motherboard also. If you have a mobo that can handle overclocking Quads, it certainly is worth it. If your motherboard is so so only with overclocking quads, stick with the dual core, you'll get more out of it.

It depand on you needs.

For pure gaming youll need to OC a lil bit. The mobo+ram can limit your OC capability.

Be sure to have a GOOD psu if you dont want to fry the whole thing.

My opinion is that its WORTH IT !

Have fun !!

The Q9550 is not a quad core processor. It is a Multi-Chip Module.

That's why Intel called it "Core 2 Quad". Two cores placed side-by-side (core 2) in a Multi-Chip configuration, "Quad".

The problem with a MCM is, both cores communicate with each other through a narrow gateway.
A MCM will not run as fast as a Quad Core processor because of it.

Theoretically yes, you're right. But since memory bandwidth is not an issue most of the time, a 'fake' quad performs very well. That would be my recommendation to the OP as well. Quad all the way! 'Fake' or not :)

enigma067 is searching for pooo where there no pooo ....

Your right for the THÉORICAL fab of those chip ... but those can stil be called QUAD. Or maybe you want us to call them Core 2 DUODUO ?
 

How much of a quad can you use?
For gaming, there are very few titles that can use more than two cores.
For other applications, maybe.
Turn on the task monitor, and performance monitor. Track your actual core usage and cpu usage. Then you will get an idea it more cores will help you.

You'd be surprised. Here's a screenshot i took of my core usage while playing the original FEAR.

I was scratching my head a bit myself. But i double checked nothing else was running, short of Firefox and a temperature monitor.
 


Eyeballing the graph, It looks like two cores are about 40%, one at 30%, and one at 10%. If that was compressed into two cores, it would look like 40% + 10%, and 40% +30%, or dual core utilization of 50% and 70%. Windows will dispatch all available cores, it does not necessarily stay on just one all the time.

^^^ agreed, windows takes the load to all the 4 cores.

Playing an old game can show a split core usage cause cause windows wil dedicate one core for the game, and other one for other apps/directX/ad others ...

So r u saying there is no real quad core on the market?

Nah, he's sayin' the Core 2 Quads aren't technically 'real' quads. The i7 and Phenom quads are 'real' quads. But it doesn't really matter either way.
 


The Core 2 Quad is a real quad. It has 4 cores, therefore, it is a quad core (whether or not those cores happen to be on the same die is somewhat irrelevant for definitions). A fake quad would be like some of the Pentium D Extremes that intel released with 2 cores and hyper threading, so it looked like 4 to the OS.

Now, in bandwidth limited apps, it is true that the Core 2 Quad will fall behind the Phenom and i7 designs, but almost no desktop task is bandwidth limited, so it is a somewhat irrelevant point. Enigma is just looking for some way to make intel look bad, since he is a rather adamant fan of AMD. Besides, the Core 2 Quad actually beats the Phenom in almost any desktop task, and is roughly even with the Phenom II, showing that it is in no way inferior to a native quad core for home use.

As for Intel's naming, Core 2 has nothing to do with the number of cores - it is the architecture (Second gen core architecture). That's why the dual cores aren't just called "core 2", they're called "core 2 duo" (I.E. Core 2 architecture, dual core). Hence, Core 2 quad is in no way Intel's admission of its status as a fake quad (which is isn't), it is simply stating that it is a Core 2 architecture chip with 4 cores.

Riiiight, which is why AMD is currently faster than Intel with their "native" quad designs. Oh wait, they aren't...
