The GeForce GTS 450 is the first DirectX 11 mid-range graphics chip released by NVIDIA, and today we are publishing the review of the NVIDIA reference model. Let’s see if video cards based on this new chip are worthwhile buying.

The new GTS 450 comes on the same price range as the GeForce GTS 250 with 1 GB (which is a DirectX 10 part), making it to compete directly with the Radeon HD 5750 and indirectly with the Radeon HD 5770 (as it is a little bit more expensive), which are on the market for almost a year now.

In the table below we list all the main technical specification of the video cards included in our comparison.
