I'm looking for a card to allow me to play Guild Wars 2 (to be released soon) @ 1440x900. Due to the high temperature in my city (37º C / 98º F today) I must choose a low tdp card as far as possible. Therefore temperature is my main concern.
I like the MSI model because of the nonexistent OC and the two fans plus a big heatsink (aluminium apparently).
From Sapphire, I like the brand: I mean, I trust them.
Asus' DirectCu system with the copper heatsink looks good.
And Gigabyte... well I find it a bit too OC'ed with a poor cooling system.
id personally go with the gigabyte model because of the largest fan . better oc and gigabytes reliability
Honestly, at first sight I thought the fan was smaller. Unfortunately, I've had bad experiences with Gigabyte's graphics cards and newegg's customer aren't talking very well about its reliability: link.
