Hey so this is my first system that i have built / overclocked.
And i just wanted to know your guys opinion since your the experts.

So specs:

Intel Core 2 Quad Q9450 2.66 Ghz @ 3.7 temp: 63
Asus P5Q-E
Corsair RAM 2x2GB - 667Mhz @ 801 Mhz
Nvidia GeForce 9800 Superclocked / Watercooled
DvD R/Wr
320 Gb HDD
500W Power
D-link Rangebooster n wireless card.
Samsung 2253BW 2ms 1680 x 1050
Win XP - 32bit
..................................................................................

Also i would like to change my Dram timings. but i don't want to mess them up since i know nothing about that, but i guess i will save it for the O.C forum.

Anyways, comments?

why windows XP and why the HDD is just small compared to systems with the similair specs you have their/

Apart from that then that is a beautiful system you got running there and when I grow up and get a job then I'm going to build a system similair, (well with modern hardware...)
