The Guru of 3D posted a review on the HiS Radeon X1650 PRO Video Card

ATI just had to bring something new in that mid-range segment by either shifting performance or price as NVIDIA had a clear lead with their 7600 series. ATI had introduced a number of "patch products" such as the X1800 GTO to remain competitive in the mid-range graphics cards segment. Along these lines it was obvious that the X1600 was not powerful enough to have a superior answer to NVIDIA, and that's where the X1650 Pro now comes in. It's release was really silent and snuck into the product line with stealth. It's a relatively cheap product that can still offer some good performance for your bucks.
