NVIDIA's GeForce GTX 295 Series has been the King of the Hill in graphics cards performance for quite a while now. The initial design was based on two PCBs with one set of GPU, memory, voltage regulation each. Now NVIDIA has updated their design to cram all components onto a single PCB. While there was some speculation about such a product, many people thought it impossible to be realized due to the large die size and heat output of the NVIDIA GT200 GPU design.
Just like the original GeForce GTX 295, the single-PCB GTX 295 comes with two 55 nm GPUs that each have 240 shading units, memory bus width is 448 bit per GPU and each GPU has 896 MB of memory available. The clock speeds have remained at 576 / 999 MHz. So in essence the performance of the "new" GTX 295 is unchanged to the old one. This also explains why NVIDIA has not released a new product name for their new card generation. This makes it more difficult for customers to spot the right product they want, something like GTX 295+ would had made sense for that. On the other hand many people (us included) would probably complain that there were no real performance improvements in such a product.
Mushkin's GeForce GTX 295 follows the reference design specifications, with the only differences being the sticker on the fan hub and the accessory package.
