Thermaltake ToughPower 750w
Seagate 500GB SATA Hard Drive
EVGA 8800GTS 640MB O/C'd to 650/950
ASUS D/L SATA DVD/RW

Case is an Akasa Mirage.

My Pc idles currently at around just under 38'c and under load usually around 48-50'c, I have a good alluminium Mirage case with two 12cm nexus fans and the CPU cooler.

I challenge myself all the time to beat my current 3DMark06 score, and am fast runnign out of ideas, last night i cracked the 11k mark, with 11178.

And i want more power! Is there any more tweaks i can do to boost up my score? is that a good score for my spec?

thanks!!
