In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce GT 320 are noticeably better than the Nvidia GeForce 6800 Ultra.

The GeForce GT 320 was released over three years more recently than the GeForce 6800 Ultra, and so the GeForce GT 320 is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 Ultra when running the latest games.

The GeForce GT 320 has 768 MB more video memory than the GeForce 6800 Ultra, so is likely to be much better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The GeForce 6800 Ultra has 9.9 GB/sec greater memory bandwidth than the GeForce GT 320, which means that the memory performance of the GeForce 6800 Ultra is marginally better than the GeForce GT 320.

The GeForce GT 320 has 72 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the GeForce GT 320 is 89 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce GT 320 having 80 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce GT 320 delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 Ultra.

The GeForce GT 320 requires 43 Watts to run and the GeForce 6800 Ultra requires 124 Watts. We would recommend a PSU with at least 300 Watts for the GeForce GT 320. The GeForce 6800 Ultra requires 81 Watts more than the GeForce GT 320 to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the GeForce GT 320.

GPU Mini Review

Mini ReviewGeForce GT 320 is an entry-level GFX based on the 2009, 40nm, second-generation unified architecture.
It's based on the GT215 Core and offers 72 Shader Processing Units, 24 TMUs and 8 ROPs, on a 128-bit memory interface of standard GDDR3. The central unit runs at 540MHz and the memory clock operates at up to 790MHz.
Its performance lies around GeForce GT 230.
Today's modern demanding games will have to be played at low (most) or medium (some) settings to achieve fluent frame rates. DirectX 11 games aren't supported.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
