According to some sources NVIDIA's NV45 won't be launched soon. This is positive for some of NVIDIA's partners who want to focus on stuff that they can sell, and that's for the moment the NV40 GeForce 6800 series.
Nvidia is actually shipping some NV40s to companies such as Falcon and maybe even Alienware, but they're still as rare as hen's teeth, particularly here in Europe.
Some samples are available in Europe and a few of the press chaps have samples too, but we all know that's very different from being able to buy them in shops.
The NV45 is the NV40 with the bridge tech placed on the same chip. Informed sources see NV45 as not making a big impact until the end of the third quarter or even the fourth.
It will be fun to plug Geforce 6800 Ultra, NV45 into a PCI Express slot and NV40, Geforce 6800 Ultra into the AGP slot on VIA K8T890 or Intel modified 915 boards, like the one we saw at ECS, and to carefully note the the difference between the AGP and PCI-E bridged card.
