hello all,
Just purchased a new rig after my last one got stolen. Its not that awesome i know. but what i need to know is that:

1> How much can i OVERCLOCK(had written upgrade making it a silly question)EDIT) and what method would you recommend?
2> How the hell do you increase the hardisk score beyond 5.9? Really annoying when everything else is 7.4!

CPU: Q8400 quad
RAM: XMS2 @800 2 sticks (was considering installing a fan on top of them as well later on)
Mobo: Asus P5QPL (will install a fan on top of southbridge and northbridge as well later on)
CPU Cooling : Corsair Liquid Cooling Kit Hydro H50 for the cpu
Native Resolution: 1080p
GPU: HIS 4890 icooler x4
Casing is : CM Elite 334 NV edition....

Currently i got only one fan in the front for taking air in the rig...
No place left for installing a new fan, any recommendations? WIll upgrade to cm 690 NV Edition later

Is it possible to get the speeds to 4.0Ghz? What would i require?

Also the motherboards i can purchase are the ones on this website ONLY :

1.) Well, your system looks fine although if you do want to upgrade your CPU, I suggest you go for the Q9400 or Q9550 if you have the cash.
2.) You need to get an SSD, or possibly a SATA III drive.

Out of curiosity, and if you don't mind me asking, how did your previous rig get stolen?

1> i just got the Q8400 so no cash left for upgrading now!
2> Yes ill get an SSD soon!

3> when i built it it was in my car to bring it hijacked at gunpoint and all. good thing, i escaped, next good thing: got a car back in one piece....bad thing:computer worth 1800pounds vanished!

4ghz on a Q8400 is very unlikely, as you would need 500FSB.

3.2-3.6ghz is a more realistic goal.

Thank god for concealed weapon permits! (Looks at browning high power 9mm on waist)
