    Wow, If you hadn't mentioned it I would say this was written by an experienced reviewer, Lsd! Very good first attempt at doing a review. I especially liked the photos.

    One small comment, though. Would be more helpful if there is a price comparison made of this 4890 with similar performing NVIDIA and ATI current offerings (GTX275? 5770?) so that buyers will be guided better in choosing their next card?

    Cool, thanks!!

    Took me a while longer than expected, but I thought I needed to make it as thorough as possible since it was my first GFX review.

    Thanks for the thoughts on price comparisons, I will keep that in mind for future reviews! I have a review I will be starting work on very shortly for a GIGABYTE card so I will be sure to add something along those lines to it.

    Hi, is the Toxic version better than the Vapor-X version? Since the Toxic too has Vapor-X technology & a much higher clock but i heard that they tend to run hotter & louder than the Vapor-X version. My question, if I were to buy a Sapphire card & choose between a Vapor-X & a Toxic version of the card, which would i choose in terms of:

    • Performance
    • Price
    • Power Consumption
    • Temperature
    • Noise

    Thanks

    It depends on what you are looking for. Vapor-X is cooler and quieter, but has no voltage control so not sure how the overclock end of it compares.

    Personally I'd just get a stock card and buy your own custom cooler. In my experience , something like the Scythe Musashi Scythe "MUSASHI" Twin-Fan VGA Cooler is both quieter and cooler than the Vapor-X coolers, which aren't IMO all that great. Sure they're better than stock, but so is a piece of tin foil stuck to the chip with adhesive tape and placed in the oven at 400F. :)

    Recently built two systems with HD4890's (had a couple of stock ones left and bought in a Vapor-X model by request) about 5 months ago actually. The Vapor X card was at about 70c at full load, and the Scythe cooled stock card only hit 66c. The Musashi cooler was also noticably quieter even set to maximum (you get a seperate back plate with two potentiometers to adjust the speed independantly.

    The only thing you have to take care of with after market coolers is the VRM's. These things can hi over 100c even when the GPU is well within range, if not cooled propperly. Grab some copper/aluminium heatsinks for them. The Scythe Musashi has, idealy, one of the fans right over the VRM's on my pair of 4850's so they stay exceptionally cool. With the stock Asus cooler and no heatsinks on the VRM's, the card crashes at 685 core and 1000 RAM. With correct cooling I'm running at 725 core and 1100 ram and could push it to about 740 core if I wanted to.

    One might think that having a factory OC'd card is a safe bet, but I have yet to see a stock 4890 that can't be OC'd to very near 1000MHz core. For this reason I'd recommend the Asus range of voltage controllable cards. Even a regular stock card will hit the same speeds as the mentioned Saphire cards with custom cooling.
