I personally prefer sapphire, except if u crossfire there wont be much space in between the cards, but there will be enough. not sure about powercolor, but sapphire is usually cream of the crop for radeons..
Well sapphire for sure. Powercolor is a budget brand.
Asus is way better than sapphire. Much cooler and quieter. And also better Ocer.
well i think asus is better in core clocks and memory compare to sapphire. in this case i can stretch my budget till $300 but if 7870 is ok and cheaper why not buy the cheapest one right if its just a little speed.
Actually the Asus one is cheaper. Just 220 after reabate while sapphire is 240 after rebate.
