NVIDIA's decision to drop the price of their GeForce 9800 GTX Series brings them back into the game on the $200 market. However, ATI's new HD 4850 will give them some competition with all of its new features. Still, at this price point the GeForce 9800 GTX is a viable alternative, it certainly offers the performance you need to play the latest games. Additional features like HDMI+Audio will make it easy to hook the card up to your big TV screen via digital connection, the HDMI adapter is included in Leadtek's package.
Our Leadtek PX9800 card showed huge overclocking potential of about 25% on the core. So if you are an overclocker you can probably make it beat the HD 4850 after some tweaking. Unlike AMD's new graphics card the overclocking tools are out there and are working great.
Another important plus is that all GeForce 9 cards support NVIDIA's implementation of PhysX via CUDA. Rumor has it that ATI will add such a feature at a later point too, but it remains to be seen if their version will be a good as NVIDIA's.
