Re: Official GeForce GTX 280 and GTX 260 reviews thread!
What was expected? Something that will outperform the GX2 considering it has a lot more optimised execution units, larger register file, higher texturing performance, 140GB/s bandwidth vs around 70GB/s for the GX2, 1GB framebuffer so it doesn't choke once you go over 512MB of textures like the 512MB cards do when you use super high res and AA and it won't have the micro-stuttering that cripples both SLI or Misfire multi-GPU solutions.
Micro-stuttering is easy, it's a single GPU so it doesn't have that. Everything else, so far not delivered upon yet.
