I'm looking at getting a used computer with a SAPPHIRE HD5870 2GB GDDR5 (Eyefinity 6 Edition).

I need some honest opinions. is it worth it? Would it be worth getting a second one to run crossfire? Or should I sell the card and buy two regular 5870's? Like these: http://amzn.com/B002QEBGG0


Thanks Yall.
