    nV release the 7800GT

    http://www.nvidia.com/object/IO_24922.html

    As ever, Brent from [H] has produced a decent write-up:

    Therefore, what we have here is a GPU that has all the same features as the GeForce 7800 GTX except that it has 20 pixel pipelines versus 24 and 7 vertex units versus 8. The GT’s core clock speed is running at 400MHz versus 430MHz on the GeForce 7800 GTX and the memory runs at 1GHz versus 1.2GHz on the GeForce 7800 GTX.
    Folks that liked the GeForce 6800 GT for its lower price and similar performance to the GeForce 6800 Ultra will definitely be interested in the GeForce 7800 GT for the same reasons. It offers performance levels that are very close to the GeForce 7800 GTX for a lower price. I

    All the reviews for this new card seem to show that 24 pipes are a waste. The four extra pipes of the GTX seem to make no difference at all. On a clock-for-clock basis the GT and GTX are pretty much dead even.

    There are already factory overclocked 7800GT out there (445/1070 for eVGA, 425/1050 for BFG) so the manufacturers seems to have come to the same conclusions too. That should be a nice alternative to the full fledged 7800GTX...

    And NV can salvage more GPUs! How convenient.

    The Inquirer is saying the RV515 and 530 are both ready to go, but ATI is waiting until after the R520 launches. Those are the low and middle end cards and include SM3.0+ and H.264 decoding like the faster R520. It will likely not hit until a month after the R520 comes out and that will likely be another 1.5-2 months do to a new stepping to improve yeilds.

    well this just killed the pricetag of a 6800ultra since you can get this for $300 shipped

    Dell Home has this BFG Technologies GeForce 7800GT OC Video Card (256MB, PCI Express x16, Dual DVI, 2D/3D w/ VIVO - SKU: BFGR78256GTXOC) for $489 - auto 20% off - $60 off $500 coupon M2VMLSN9QBGT3T = $331. Search for BFG GeForce 7800 GT to find it.

    Add this $12 CD-R to pass the coupon limit.

    get a $35 off 300 coupon from dell and this be yours for $300

    Using those same coupons, you can get the 7800 GTX for $332. But as good as those deals are, I think I'll be waiting until the next generation of cards to upgrade. Maybe when they get rid of the pixel pipelines and make cards whose fillrate actually makes use of their theoretical capability.

    This should change as we move towards more shader-centric games (could be noticeable when the wave of XB360/PS3 ports arrive). But for now, you're right, they're pretty much neck and neck.

    The best thing I like about this card though is the power draw. It is much lower than the GeForce 6800U and 7800GTX... like half as much....

    http://www.anandtech.com/video/showdoc.aspx?i=2496&p=10

    16w less than the 7800GTX and 27w less than the 6800U at idle (total system power draw). Under load it is even better at 49w less than the 7800GTX and 58w less than the 6800U. If they used an 80% efficiant power supply, then the 7800GT is about 45w less at full load. The 6800U runs about 120w max, so this card likely runs in the 65-75w range under full load. That is on the range of something like the x700Pro or 6600 non GT for power draw. That is VERY impressive. Since it has H.462 and Pure DVD stuff, and a low power draw, this would be great for a powerfull HTPC or SFF that can game too.
