So I think its about time I should upgrade my system to keep up with some of the newer game titles. Right now I have a sapphire radeon 7870 oc edition and I'm not sure quite what to do. It hasn't been long enough to buy a brand new card (I personally will wait another year or two for that) so I want to stick with the 7000 series. Also I want to buy on the lower end of the price spectrum, so my choices as of now are as follows: buy a sister sapphire radeon 7870 OC refurbished from newegg for ~ $135 or buy a 7970 GHz used from ebay/amazon/local for under $200. (yes I know buying used computer equipment from people can be "dangerous" but I'm willing to risk it). I want multiple second opinions before I make a decision. If you have a suggestion that is different from my two I will be more than glad to consider it as well.

BTW. I'm running two monitors and I have a 700W PSU from OCZ. pretty sure this is it.
