I just finished my first build... I bought 2 ASUS R7-260X's. Now I understand that these aren't the top of the line R series GPU's... but they do have many of the same features as the more expensive ones. These 2 GPU's in CrossFireX work very nicely, and we have had no problems with them... I own many ASUS products and I trust the brand (I never consider buying any other if ASUS has a competitive model). What made me choose this brand and these specific GPU's is the fact that they came with $80.00 worth of free games each when I purchased them from newegg... so by buying 2 we got $160.00 worth of free games which virtually means we got a free GPU with a little extra! Plus at this price point these were the only GPU's that had AMD TrueAudio built in. You simply can't go wrong with ASUS gear and it seems silly to me to compromise by using other brands. I also like how ASUS is actively putting out vids on Youtube for new/experienced pc builders to gather info, by the way... that dude JJ really knows his stuff and we learned a lot by watching his videos. ASUS is the best period.
