NVIDIA are still riding the success-train of the GTX580 launch (with various countries experiencing way shorter than usual stock levels) and have now launched the GTX570. We talked about this not very long ago with spec details but pricing eluded us at the time.
The Palit GTX570 info we posted is still correct - 732MHz core, 480 CUDA cores with shader clocks at 1.4GHz. Pricing is set at £299 including VAT in the UK. This is interesting as it's now £100 more than the GTX470 but £100 less than the GTX580.
Hopefully TweakTown get a review sample this time? nVidia, please be our friend.
