Just bought mine yesterday(+whole rig). Not that noisy... but I think I'll need to test again, without using my headphone. No time for that though, need to stay on campus for 2 weeks cry.gif

Now my big bro will play it instead lol doh.gif laugh.gif

Dont need 1k, it is and overkill 850 is more than enough to power up.
Its even can run with a 750w real power psu.
Im using corsair tx850w.

It can run crossfire even its not certified.
Single rail provides the best stable output.
Its not noisy and TX series is a very popular tier 1 psu.

This is what I get before and after I OCed both GPU and CPU. Is it ok or should I achieve more than this?

Anyway, I wanna try to OC it to 1GHz but a little afraid to pump up the GPU voltage. I'm not using any after market cooler.. So, any advice guys?
