With the HD 4870 X2, the 2GB of GDDR5 is so each GPU can address 1GB of storage, which makes more sense than giving each core only 512MB.  It was inevitable that someone would try slapping a full 2GB of GDDR5 on a single HD4870 core, and Sapphire seems to be the first to hit market with it.  The Sapphire Radeon HD4870 2GB will run you more than the 1GB version, so the question becomes one of performance.  Can the extra memory push this cards performance higher than it already is?  TECHGAGE has the answer here.

“Believe it or not, despite the HD 4890’s launch last month, the HD 4870 is still totally relevant, thanks to ATI’s current pricing structure. There’s a card for every budget, and if you’re willing to spend around $180, you can get hooked up with a 1GB version of the card we’re taking a look at today. It’s silent, keeps cool, and still delivers great performance for the money.”
