i have used a few Palit GPU's, in my area their RMA process is very very nice. If they find it faulty, people got a replacement within an hour. of course given that the gpu was used and cared for properly.
while i like other brands (like asus), i also like cheaper brands like palit. Now i am using Innod3d, i did not like them before, but after reading about the review of my gtx670 i bought an inno3d ichill. and man, this is the coolest running gpu i ever owned. i play bf4 with a temp of 49-50. my previous 560Ti MSI twin frozr using the same pc in the same room and same game, it was running at 63 and above. Very very nice, though i chill is not that cheap, but worth it
