    go with the 9600 or an 8800GT
    both of them out performs two 8600GTs in SLI

    also, that EVGA 8600gt is 256mb 128-bit
    two of them in SLI will NOT give you 512MB 256-bit, it would still be 256mb 128-bit.

    for that budget, I'd recommend this one
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814127333
    great cooler, factory oc'd to 700MHz.

    only 1 yr warranty though.
    if that is important to you, EVGA or XFX = lifetime warranty
    plus EVGA has that step up program. your call.

    I was wondering why the 8600gt wouldn't pump out 512 if it is SLI capable?

    that's just how SLI works.

    it doesn't double you video RAM, what it does is it duplicates the contents of the video RAM (one copy for each card) so the two GPUs can share the workload.

    to expound on that:

    the only thing required in SLI is that:
    1) the cards are SLI capable, and
    2) same GPU chipset

    you can mix different manufacturer, clock speed, ram size, etc.
    but here's the thing,.... SLI will always use the worst specs.

    if the cards have different clocks speeds, SLI will use the slowest one.
    e.g. Card1 - 700MHz & Card2 - 650MHz = 650MHz in SLI

    if the cards have different RAM size, it will use the least one.
    e.g. Card1 - 256MB & Card2 - 512MB = 256MB in SLI

    this is why identical cards are recommended because it is guaranteed that it has the same GPU and no resources are wasted.

    always remember in SLI, 1+1 = not 2
    but it does double power consumption and generates twice the heat.

    I use an EVGA 780i SLI MOBO, 2 EVGA 8800 GTX's w/768 MB and I like them just fine ...

    I don't have water cooling so I don't over clock them as hard as they could go just yet. I'm working on routing some flex tubing and giving the unit it's own A/C source.

    This will answer most of your questions about SLI ... it is quite easy to use and set up. Like Doomsday said there is quite a bit of latitude but it works best when things are compatible.

    EVGA has EXCELLENT Support (I know this from personal experience) ... do the step up program and cross ship too.

    XFX has a lifetime warranty which is good but...I have an XFX right now and I've had to send it in for warranty replacement 4 times in a year. ~2 week turn around on receiving the new card means my computer has been down a full month in the last year due to warranty replacements.

    Just something to think about.
