    here the comps:
    -RAM DDR3 Corsair Vengeance 1600MHz 8GB (2x4GB) CL8
    -SSD Crucial RealSSD M4 128GB 2.5" Read 415MB/s Write 175MB/s Sata3
    -PSU Xfx 750W Black Edition
    -CPU Intel Core i5-3570k 3,4GHz Socket 1155 77W
    -MoBo Asus p8p67 WS Revolution

    i'm going to xfire, i dont know whether to take a 2-space Iceq X / DCII or a normal one 10€ cheaper.

    just to know will two 2-space cards fit into this? (with a tower case)

    Well for starters that Motherboard you posted is a Socket 1366? Your current specs? It will support X-Fire. Are you not building a new one?

    Do you not have any Sapphire 7870's available? They are usually better priced than most and always come with a great bundle. Not to mention they have always been AMD/ATI's biggest AIB partner so your gonna get a good card.

    I recommend the sapphire 7870. I'm currently using one and it's performing quite good.

    Can do 1100mhz core with default core voltage.

    It looks a little tight on the 1366 board but should fit.

    See another vote for Sapphire ;)

    Been using Sapphire as far back as I can think of(X800 prolly) Never had an issue with them. They have always been ATI/AMD's biggest AIB partner. The ATI branded cards were "Sapphires" just changed the stickers.

    My DCII can run at 1150/1300 on stock voltage. Of course, what our cards can do....means nothing as far as any card the OP may buy. He could get a better card....or even a worse card.

    How is XFX compared to Sapphire in terms of longevity/power consumption and noise ?

    There are actually 4 listed on the Asus website, the original versions and the v2 versions. They actually look quite different. Not only is the cooler different, but look at the circuitry below the cooler:

    Non-turbo HD7870 DCII
    old: http://www.asus.com/Graphics_Cards/AMD_Series/HD7870DC22GD5/
    new: http://www.asus.com/Graphics_Cards/AMD_Series/HD7870DC22GD5V2/

    Turbo HD7870 DCII
    old: http://www.asus.com/Graphics_Cards/AMD_Series/HD7870DC2T2GD5/
    new: http://www.asus.com/Graphics_Cards/AMD_Series/HD7870DC2TG2GD5V2/

    In terms of features, the only difference between the turbo and non-turbo's is the clock speed (from what it looks like). the 1010 clock speed is the version 2, the original version was 1000.

    from the links the 1010mhz is the original version.

    there is some improvment from the basic version to version 2 that you know of?
    i dont see DVI-D on basic

    im now undecided between gigabyte winforcex3 and old Non-turbo DCII
