khaled my friend, pcandparts and microcity along with all distributers are limited to 1 big company, most of us know its name.
The item in my hand is i5 2500 K, K series have unlocked multiplyers and can oc way way way beyond a non K variant. Pcandparts and microcity have 2500 non-k, which can slightly oc. You can get it to 4ghz if your lucky, since the multiplyer is locked you will have to oc the baseclock from 100 mhz to 103-4 IF your lucky, also upping the baseclock too high can damage cpu and degrade sata performance. A K version is unlocked keep the baseclock 100 mhz and multiply by 44-48, you can get 4.4ghz. Anyway the rest of the pc wil arrive from pcandparts dont worry about that.
But again i stress NON K version of the 2500 exist in lebanon's retailers, the only K sold is 2600 and to me the price difference is useless, we saved $ from here and there and put all our efforts in the gtx 570, gpu matters more than cpu :).
Concerning the 570 and why i chose this card over the reference gtx 570 is because of the issue with vanilla gtx 570 accompanied by oc and overvoltaging.
I had 2 choices this card and pcandpart's msi PE, the asus card costs 500$ from Republic of gamers store after the guy gave me a discount while the msi from PCandParts is 488$ add vat and 5$ shipping the price is 542$. So i saved 42$.
Second reason i didnt buy msi, though i love their gpu lineup, is because this particular MSI gtx 570 Power Edition OC is EOL. Msi does not make it anymore, lets say after a few month the card died, what will i do??
In usa msi is giving refunds to these cards, we are not in USA :S...
