It's clear that companies are going to offer the HD 4890 for months to come, even though the HD 5800 series are just around the corner. Really, at the end of it all if the chips are available you're better off selling them instead of having them just sit there. But due to the model being out for so long, no one wants to see a flurry of reference cooled and clocked models come to the market.
Instead companies like MSI, HIS and Sapphire have decided to really mix it up by offering new cooling solutions and new overclocks. From the cooling perspective the Cyclone cooler that MSI use doesn't offer any better performance than some of the other new cooling options. If anything, the size of it is more of a pain due to the fact it kills your ability to use CrossFire.
What the cooler does offer, though, is looks. Honestly, the cooler looks so mean and until you have it in front of you on the card you really don't realize the coolness of it. The Military Class specification for the card also seems to help keep power draw down in load situations.
We've got a decent cooler, some good performance thanks to the overclock and the Military Class marketing seems to actually be useful by dropping down the overall power load of the card. While the bundle might be a bit lacking, if you're after a HD 4890 that performs well and looks good, the MSI offering is a good choice. If you want a bit more power it might be worth looking at the SOC offering that offers even higher clock speeds.
For your reference, the MSI Radeon HD 4890 Cyclone OC 1GB graphics card
can currently be purchased over at Newegg for $184.99 after a $15.00 mail-in rebate.
