  1. so Rage saved me so much money on my intel quad system this fall i decided to use the balance to build a gaming system i have wanted to build for a while, a 3x crossfire system. and one of my favorite aspects of this site is posting new builds and ya'all commenting,impughning,admonishing,and castigating on ones choices. the parameters were....1) 3-way crossfire
    2) 790FX chipset
    3) Dual core
    4) $600 or less

    So heres the pile of just delivered hardware on my workbench, let me know what you think, and or what kind of performance you think it will yield.

    Graphics x3

    re-using Hdd's and optical. going to OC the x2 7750 to 3.2-3.4Ghz

    All your picks are oK. I would be very careful about the heat sink as there are many cases in which it will not fit, or will cause you fits as you try to install it. All other choices are OK.

    hey kitty,
    im a big fan of amd gaming platforms and the 790FX chipset. as far as the 3x CF, its a enthusiast thing mostly, and a $ to performance deal 1920 SPU's, 2.5 TF's. for $250. it will be interesting to see how CF improves as the drivers for it mature. right now im betting that the third card will have little impact, but who knows with the 9.1 drivers out now.
    read your

    oh wait, i misread your question. yes im CF'ing 3 4830's

    For a PSU, I recommend the 650TX, for maximum stability. The 600SXS may not cut it for three cards and an OC'd Phenom.

    Everything depends on the quality of the build on the PSU selected. 550VX is enough if the power supply is well built, and 650TX is not enough from a cheap build. The power supply one uses has so very little do do with power rating. High power does not necessarily make a power supply more stable.

    Err I was referring to a particular PSU raybay, the Corsair 650TX. Sorry if that wasn't apparent before.

    FYI, the 550VX is also a Corsair PSU.

    EDIT: Sorry Greg, I thought you hadn't bought the parts already. The OCZ PSU is okay, but OCZ's PSUs usually exhibit extremely high ripple on the +12V rail as soon as the load on them goes beyond 80% of their total rated capacity. But the HD 4830s require only 350W or so in total, so you'd be fine.

    thanks Moiz,
    i did have a senior moment though when i decided to go 3x CF and didnt change the psu accordingly....DOH! sent me scrambling for the antec psu calculator! lol.and your right, the 4830's are rather efficient and looks like a good 450W would have done fine. thanks Moiz-cheers
