G70 ~ GeForce 7800 info + reviews

    most interesting thing I've noticed is that even though G70 ~ GeForce 7800
    GTX has 24 pixel pipelines
    or pixel shader pipes, it only has 16 ROPS and therefore can only output 16
    pixels per clock.

    I will post more reviews as they start to come in, since the NDA expires
    Tuesday night in the U.S.

    so no AGP version. Ok, I need a new motherboard with PCI express
    too...wait, Xeon boards are now 800fsb so I'll need new
    cpu's....memory...psu....box...a whole machine really. So to upgrade my
    graphics it's a snip at £4,000.....bargain.

    You have a Xeon? Anyway, if you get a new board, the FSB can still be set to
    a lower speed to match your old CPU and RAM.

    Unfortunately, the only relevance to me of the 7800 is whether or not it'll
    drop the price on the 6800 Ultras :^(
