Even though the Point of View GeForce is a great card offering plenty of performance its success will be limited by AMD's Radeon HD 4870. At this time the HD 4870 is $100 cheaper while offering very similar performance. The only scenario where I could see the GTX 260 gain an advantage over the HD 4870 is when more than 512 MB graphics memory is used, which may be the case when running 2560x1600 resolutions. Another advantage of NVIDIA's GPUs are that they have full support for CUDA's GPU accelerated computation and also NVIDIA PhysX. However, at this time there are not many applications for CUDA/PhysX but rest assured, NVIDIA will make sure this changes.
Point of View's GTX 260 includes a unique game bundle with Assassin's Creed, a recently released top title. In order to fight ATI's products, NVIDIA will most probably reduce the price of the GTX 260 and GTX 280 in the near future, so holding off for a bit with your purchase might be a good idea. Our GTX 260 sample showed amazing overclocking potential, easily reaching GeForce GTX 280 levels, and this is something most ATI HD 4870 cards won't achieve, at least not with stock voltage and cooling. Also the overclocking software support on ATI side is rather limited while on NVIDIA everything just works.
