The first thing we have to say is that there's a solid performance increase across the board when it comes to the Sapphire HD 4890 2GB Vapor-X. We can honestly say that most of that gain would come from the increased overclock more so than the extra memory.
Does that make it a waste of money? Not really; the Vapor-X offers more than just some extra memory. For around $250 U.S. Dollars you're getting a new cooler which while it doesn't cool quite as well as the stock one, does a good job of dropping noise levels. You've also got a bump in core and memory clock.
If you want 2GB of memory on a graphics card and don't want to break the bank, the Sapphire Vapor-X model we have here today is pretty impressive. The good news is that if you're not interested in spending the extra money that the 2GB card carries, Newegg also offers a 1GB version for $219.99.
We've got a solid card here that's going to be a good option for some people. If the bundle, cooling and overclock wasn't enough to get you excited, the decision to implement display port and HDMI natively to the card could be the deal clincher.
