GeForce GTX 400 Series Performance Expectations Hit the Web
A little earlier this month, NVIDIA tweeted that it would formally unveil the GeForce GTX 400 series graphics cards, NVIDIA's DirectX 11 generation GPUs, at the PAX East gaming event in Boston (MA), United States, on the 26th of March. That's a little under a month's time from now. In its run up, sources that have access to samples of the graphics cards seem to be drawing their "performance expectations" among other details tricking in.
Both the GeForce GTX 480 and GTX 470 graphics cards are based on NVIDIA's GF100 silicon, which physically packs 512 CUDA cores, 16 geometry units, 64 TMUs, 48 ROPs, and a 384-bit GDDR5 memory interface. While the GTX 480 is a full-featured part, the GTX 470 is slightly watered-down, with probably 448 or 480 CUDA cores enabled, and a slightly narrower memory interface, probably 320-bit GDDR5. Sources tell DonanimHaber that the GeForce GTX 470 performs somewhere between the ATI Radeon HD 5850 and Radeon HD 5870. This part is said to have a power draw of 300W. The GeForce GTX 480, on the other hand, is expected to perform on-par with the GeForce GTX 295 - at least in existing (present-generation) applications. A recent listing by an online store for a pre-order, put the GTX 480 at US $699.

Or how about the firing squad review? www.firingsquad.com/hardware/ati_radeon_5870_overclocking/
Not only does OCing the memory provide a small increase at stock gpu speeds, but it provides an even bigger increase when you OC the core speeds. As the core speeds increase, so does the need for bandwidth.
As far as the 2900 vs the 3870, I switched back to the 2900 from a 3870 because the 2900 was a better performer under water cooling with a highly OCed gpu. For anything else you want to know, you'll have to dig around in the forums for posts from around that time. There were actually a few of them.

i thought this was cool... one thing about nvidia theyre always doing/showing stuff that i think people would like to see implemented into gaming
