It's been a while since I did this, so some comments about the setup before I buy would be nice.
 
Setup:
 
Gigabyte GA-965P-DS3
Socket 775 / Intel P965 Express / 1066 MHz / ATX / LAN / LYD / SPDIF / 3xPCI-32 / 4xPCI-E / 4xDDR2-RAM
 
Core 2 Duo E4300 1.8 GHz
[Core 2 Duo 1.8 GHz / Socket 775 / 800 MHz / 2 MB L2 / Intel Boxed
 
Corsair XMS2 2 x 1 GB
2 x 1 GB (2 GB) / DUAL RAM / DDR II SDRAM / PC2-6400 / 800 MHz / CL5 / 1.9 V
 
BFG GeForce 8800 GTS OC
NVIDIA GeForce 8800 GTS / PCI Express x16 / 550 MHz / 2560 x 1600 / 320 MB GDDR3 SDRAM (1.6 GHz)
 
Antec TruePower Trio 550 EC
550 Watt PSU / Intern / AC 100/240 V / 47 - 63 Hz
 
I intend to OC (up to ~3 Ghz), and regarding this I have a couple of questions. Will the Intel stock cooler do a good enough job? Or what cooler do you recommend?
 
And is the E4300 CPU the right one to choose? Or should I go for the E6300/E6400? I think the price jump up to the E6600 is too big, therefore I'm not considering that one, unless you thing I'm really missing out on something.
 
Thank you in advance.  

 
I don't suggest Corsair's XMS. 2.1v may net you DDR2-900 speeds or even DDR2-1000 speeds if you're really lucky at 5-5-5-15 timings. Those were testing of the CAS 4 modules though. It'll do fine for the E4300 though. Although, it is a good price. I had to admit. A decent DDR2-667 module like the Super Talent one could easily hit the fastest an average E4300 can go.[/b]

Thank you for the quick answer.
 
The 6600 model is double the price compared to E4300/6300 in my country, and if it only clocks about 10-12 % better, then I think I'll stick to the "low-end".
 
Do you have any RAM suggestions? I do not intend to push the CPU (and RAM) as I have little experience with OC'ing.

 
Clock for clock it is 10-12% better. A E4300 at 3ghz is the equivalent of a E6600 at 2.72ghz. A E6600 at 3.6ghz (which is fairly possible on air) is the equivalent of an E4300 at 3.96ghz, an impossibility on air.
 
Super Talent has a great 1GB module at $61 at NewEgg. It is of DDR2-667 flavor and wouldn't have to overclock to reach 3ghz on the E4300. It is a solid overclocker and has reached DDR2-800 to DDR2-950 speeds if need be. Grabbing two of those will be fine.

Hmm, Newegg.com doesn't ship international, and the cheapest Super talent in the online stores here (Denmark) is 150$ (they only have PC6400)  
 
But thank you for your suggestion.

In that case, Ewiz has the same module at similar prices.  
 
From Ewiz's Shipping FAQs
 
Can eWiz.com ship internationally?  
eWiz.com currently DOES ship internationally via UPS Worldwide Express or UPS Worldwide Expedited. However, please make sure that a valid payment method is selected as we currently do not accept international credit cards.

Thank you, I'll look into it.
 
In regards to the CPU, why do you consider the E6300 one step above 4300?
I thought E4300 was prefered because of the higher multiplier, hence being easier on the RAM. Or am I missing something?

You are almost talking about two things even though the are related. e4300 multiplier is 9. The e6300 multiplier is 7. So to get close to the same speed, the FSB for the e6300 would have to be higher, so the RAM speed goes higher to get the same 1:1 ratio. Easier to get the speed with cheaper memory with the e4300, so if you o/c and want the best bang for your $$$, we pick the e4300.

Okay. Thank you for clearing that up. I'll stick to the 4300 then.

Looks pretty good from here.Everything except the power supply.I would get at least a 600watt or higher,preferably higher like 700watts.You can't go wrong with good solid power from a good manufacturer,and I do highly reccomend THERMALTAKES TOUGHPOWER line of power supplies as a good place to look.Goodluck.

Okay, I'll check those out. I plan on adding my 3 HDs also, perhaps I should go for more power Thank you.
