nice card runs every game i play full tilt except i had an issue on arma 2 with the dayz mod i learned going to nvidia control panel and adjusting the power managment option for maximum performance helped. Friendly reminder to those who may be experiencing lag with some high end nvidia cards, anyways cards at 55% fan speed suppossidly runnig really hot. It is still quiet but what i observed about this card a lot is the fact it likes to turn up fan speed gradually, it starts at 10% speed then when it hits around 50c (im canadian so not familiar with farienheight off hand) it boosts it up ever so slighty the fan speed that is. Later on it keeps it below 50c as best as it can for a while, slowly boosting fan speed then overtime seems to stop caring about temperature and does its own thing. That is just my experience maybe im inexperienced, maybe im over thinking temperature wise. I hope this review is helpful, im still getting use to this video card and its features etc so far though im really satisfied with this purchase if this comes down in price i would not hesitate for a second to SLI these cards.

I installed this in my Hackintosh. Kepler based cards do not require any configuration.

Runs cool and Quiet, looks sexy, made by ASUS, plays everything at 1080p on high/ultra at 30+ FPS (all you need really) I actually bought this for my HTPC I got it on sale for $179.99 and after MIR it was 159.99 and came with AC4 and Splinter Cell ($120 worth at the time) I was going to buy AC4 anyways so in my head I just subtracted another $60 from the $159.99 and it was like getting it for $100, couldn't be more happy even though its total overkill for my HTPC lolbut allows my brother to play LAN games with me now :) (Read More)
