For now, the HD 4890 is ATI's best video card besides the dual-chip HD 4870 x2. With an overclocked out of the box clock speed of 870MHz and a memory clock speed of 1050MHz, the Sapphire Vapor-X video card is faster than the default clocked HD 4890s on the market. This card is available on Newegg for $249.99 making it a $30 premium over the 1GB version of the same card. 2GB only really makes a difference when high resolution AA+AF is enabled. Also be aware of the system requirements are slightly wrong on their website.
In any event, 2GB of video card memory only affects situations where a lot of memory is required like high AA and AF is enabled, but the cost is only slightly more than the 1GB version. It's a fine line between buying a video card to have the highest frame rates and one that has a great price/performance ratio and this card meets the criteria for high frame rates with a reasonable price tag. This is a very solid card and the dual HDMI connections make it even more appealing to those building an HTPC that can actually play all the latest games. Overall this new card from Sapphire is a definite Hot Product, it excels in a few key areas and offers excellent gaming as well.
