    Cannot wait for these cards! Does anybody know if I'll be ok running 2 in crossfire with my 750w PSU (which only has 3 of those 6-pin PCIE power cables) with the fourth cable coming from a molex to 6pin PCIE adapter? its a thermaltake toughpower cable management PSU so pretty good quality (i think)

    I suggest TweakTown include the PSUs they are using in the setup page especially on reviews like video cards in CF. I'd rather see what PSU was used instead of the hard drive. Anandtech did a review of 2 4850s in CF and said "The OCZ 1000watt PSU couldn't power them so we swapped it with a 1200watt PSU." Duh--Anandtech. I told them that a rail on the 1000watt PSU must be bad because the manufacturers recommend only a 550watter for 4850s in CF(600watts for 2 4870s). I am surprised they didn't think about a massive 1000watt PSU not being about to run 2 little 4850s and just blindly swapped out PSUs. I'm gonna run 2 4870s with a PC Power and Cooling 750watt Quad as it has 2 6 pin and 2 6+2 pin video card connectors so theres the 4 6pins. Also has one massive +12V rail which I like better that 2-4 small rails.

    Iv been reading reviews from Tweak town from past 1 year. I always admired them, as they reviewed the products so excellent.
    I really don't like to post my opinion but now i have to. On internet most of my time goes in reading reviews from many reviewers.
    I really hate the way that tweak town reviewed the ATi HD 4870 because in most of the reviewers that i saw was the card was above extreme than Nvidia's GTX 260 in crossfire . But in this review i saw in most of the tests it was below 260.
    I really dont believe it....... THE END

    This article needs a re-writeup. Lots of Catalyst driver enhancements offer superb crossfire scaling now. Even in games like Crysis (50 to 70%!!).
