    Hi folks
    well basically been doing research on my mobo to see if i can replace my 560ti OC with 2 Radeon HD7870 and run them in crossfire but I'm not 100% if my mobo will be able to run it, please can the pro's please help to confirm whether I can or not.
    specs are:

    AMD phenom x4 995 3.2 GHz blackedition
    PNY 560ti OC 1gig
    Asus M4N75TD motherboard
    750w novatech PSU

    Do not run midrange cards in CrossFire or SLI. You'd more easily dip below 60FPS and that's where microstutter is present / most noticeable.

    SLI is somewhat smoother than crossfire as the drivers reduce microstutter (they do not eliminate it). However it generally scales worse than Crossfire.

    Only if you're heavily OCing those cards would I say it might be fine to Crossfire those 2 cards, but I still advise you not to.

    Go for a single high-end card with more VRAM, more bandwidth, etc... and you'd have less headache. And if you have the budget for 2 high-end cards in SLI / Crossfire, that'd be workable.

    That Phenom X4 995 would probably bottleneck the 2 cards as well, I don't know if it would bottleneck one 7870 or one high-end card (7950/7970/670/680).

    Your board is SLI not CFX

    Meaning you can run 2 x nVidia cards in SLI

    only 1 x AMD card though

    I see a massive processor bottleneck with 2 cards and an X4 but 7870's in Crossfire are beasts

    yeah that's why i would like to invest in them as I have always been a nvidia fan boy but its time to break the mould and go for radeon now i see they excel and not to mention they are more powerful than 560ti at the same price, if not cheaper.
