Hey yall about to buy a new pc here are the specs

Asus M3A79-T deluxe

2 HD4870x2's

Phenom II X4 940 @ (3.8-4.2ghz)

8 gb's or 4 gb's 1066mhz Corsair Dominator TWIN2X4096-8500C5DF
(asus says to run these @ 1066mhz you can only use 4gb's but if you run all 8gb's it's @ 800mhz) What would be better to due buy 4gb's or 8 and would it be able to OC them too?

1200 watt Thermaltech Toughpower

147gb 1500rpm Fujitsu

and for pc cooler (not sure if this is a good one but it looks cool :) suggestions nice)

So ya the memory is my question and the pc cooler is my question. I'm nervous as hell about OC'ing and afraid of water cooling so air is more what I'm looking for.
 
Generally, it's much easier to overclock with two sticks of RAM than it is with four. If you're more concerned about overclocking, then my recommendation is to stick with 4GB unless you really need the extra RAM for some reason (although in most cases, there's very little performance increase with 8GB of RAM compared to 4GB).

As for the cooler, that one isn't particularly good. I recommend this one instead:

Why would two sticks do better than four?

This is my first time considering to overclock a pc
 
Running with four sticks puts more strain on the memory controller, which tends to not overclock so well when it has to handle that much.
 
Makes sence

Does memory effect the Intel cpus since there mem controller is not on the cpu?
 
It's pretty much a blanket "rule of thumb" 2 sticks will clock better than 4. Though some people have luck running 4, the majority have better luck running 2.
 
Is there anyway to overclock the Cpu without screwing with anything else (i.e. memory, FSB, gfx cards). I know you can change the multplier but will that leave every thing else alone?

Got to remeber i havent ever really done this before.
 
Don't know if the new Phenom II's will have unlocked multipliers. If so, then yes, you would be able to OC the CPU without messing with too much else. Otherwise you'll be cranking up the FSB and adjusting memory ratios just like the rest of us. :)
 
The 940 is supposted to be a black edition at stock 3.0ghz

If you can OC it without messing with memory does that change the 2 stick rule at all?

(wanted 8gb's to kinda make fun of a friends pc. Braggn rights... Its a horrible thing)

Yes. The memory controller is built into the northbridge, so putting more strain on that will limit the maximum FSB you can achieve. Also, Intel's new Core i7 CPUs have integrated memory controllers as well.

Yeah, theoretically it should give you more headroom considering the RAM controller shouldn't be any more stressed.
