    Sapphire Radeon HD 4850 X2 2048 MB

    You'd better wake up dude... Depending on the game, even a 9800GX2 can be limited on a 16x v1/8x v2 PCIe slot http://www.tomshardware.com/reviews/pci-express-2-0,1915-12.html Some games are hurt badly in terms of performance, and can easily show the limits of the PCIe on a P35... The next I...

    Sapphire Radeon HD 4850 X2 2048 MB

    The first thing you should get is a new motherboard, the PCI 1.1 port on the current one is holding the HD4870x2 cards back where the GPU is the limiting factor, as we discussed in the feeedback thread for the HD4870x2. Try crossfire with 2 HD4870x2 on 8/8x PCIe 2.0 ports and see what gets lost...

    Sapphire HD 4870 X2

    It's how fast the the graphics card is that will decide if the PCIe port becomes a bottleneck or not. The HD4870x2 have twice the power of a single HD4870, and therefore demands alot more of the PCIe port in use. I do infact believe, that the P35's 16x PCIe 1.1 port with lesser speccs and half...

    Sapphire HD 4870 X2

    There is no difference in P45 and X48 when single PCIe is used, both has 16x PCIe 2.0. P35 uses PCIe 16x 1.1, witch is the same or slightly slower then 8x PCIe 2.0, and might be the reason for the bad scores in this review. P35 suffers badly in crossfire with it's 16x-4x PCIe 1.1 solution, and...

    Sapphire HD 4870 X2

    He is wrong, the X2 widens the gap the higher the resolution get's. And you are wrong aswell, in modern games, CPU will be less of a limiting factor the higher the resolution and AA/AF you use. If you game in high enough resolution in most of todays games, you will not see any difference between...

    Sapphire HD 4870 X2

    The HD4870x2 widens the gap to GTX280 the higher the resolution get's. How you can read those graphs so wrong is odd. Look them over one more time, and you'll se that "the popular belief" are infact the truth in this case... The bad results the HD4870x2 recieve in this review, seem to be down...

    Sapphire HD 4870 X2

    You are just underlining my points, these cards are not meant for 1024x768 0xAA 0xAF/1280x1024 2xAA 8xAF used in this review. For those resolutions to have any meaning at all on these high-end products, you'd have to slap on 16xAA 16xAF, but he did not. And thus it's a CPU bench, not a graphic...

    Sapphire HD 4870 X2

    This is a High-End product, witch only stretches it's legs on high resolutions. This is not meant for the masses, and will mostly end up in enthusiast's PC's. If you wan't to accurately review such a high-end product, using 1024x768 0xAA 0xAF is pointless, as it becomes a CPU bench in 99.9% of...

    Sapphire HD 4870 X2

    HD4870x2 is 35-45% faster then a GTX280 at 1920x1200 4xAA 16xAF on average. And even faster on higher resolutions. To get the throne back, Nvidia would need alot more then a clock bump from 55nm., alot more and way beyond what a shrink can provide. If you game 24 hours a day for a whole month...

    Sapphire HD 4870 X2

    I don't think the masses with 19" monitors are lining up to buy HD4870x2 or GTX280, some might, but those should not count :banghead: His average include 1024x768 and 1280x1024, and thats half of his resolutins. And when half of the benches hardly showes any difference between the cards at...

    Sapphire HD 4870 X2

    Well, one graph would be sweet if it told the absolute truth, but it does not. One good example is 9800GTX+ vs. HD4870x2 in 1024x768 F.E.A.R.: here HD4870x2 is only 50% faster at 3 times the price, but when you move to 1920x1200 it's close to 300% faster. It would completely change the picture...

    Sapphire HD 4870 X2

    Wouldn't it be better to have an % number pr. resolution? Slapping it all together does not tell the whole story IMHO. I imagine people would find it interesting to know that the higher the resolution, the bigger the difference between HD4870x2 vs. GTX280. After all this is a high-end part, and...

    Your timedemo is actually faster then guru3d's, by 10 fps on HD4870, and the difference between GTX280 and HD4870 is also about the same. What you are not getting, is Crossfire scaling on the same level as the other review sites, they are at ca. 1.8x, while you have 1.4x. This might be down...

    Sapphire HD 4870 X2

    No problem, mate! For some (alot actually), performance in this game will break, or seal the deal on a new purchase. So getting this one right, with twice the performance of Nvidias best, will sertainly give a huge boost for the HD4870x2, since this game is so popular and good FPS and visuals...

    Sapphire HD 4870 X2

    I was just wondering how you could mess up the COD4 benchmark so horrible, and not even comment on it. You are actually not using 2 cores at all, the difference between HD4870 and HD4870x2 is under 6fps, and thats just downright silly. Anyone with any experience at all on these HD4xxx card...
