Which graphics card should I get from these two??

[Cornerbog]

I'm buying a graphics card off Ebay but I cannot decide between the two...actually it's not that I can't decide, it's that I cannot tell if there is a significant difference.

The two cards are:

AMD Sapphure HD 7870 GHZ OC Edition

AMD Sapphure HD 7870 GHZ OC Edition Dual-X

Does Dual-X make the card significantly better?

Are you sure the Dual X is also a GHZ OC? Sapphire had so many name variations for basically the same cards, it is hard to keep track. Can you link to the cards in question?

These are the links that the seller gave on the Ebay product pages:

No Dual-X - http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1160&pid=1487&psn=&lid=1&leg=0

Dual-X - http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1160&pid=1744&psn=&lid=1&leg=0

If you want the Ebay pages as well:

No Dual-X - http://www.ebay.com.au/itm/151433692155

Dual-X - http://www.ebay.com.au/itm/151433709204

They links take you to basically the same page, with a slight difference in the URL and two different pictures

According to the Sapphire links, the Dual X has a slightly slower memory clock. Other than that and appearance, I see no difference.
