In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6150 LE are noticeably better than the Nvidia Quadro NVS 280.

The GeForce 6150 LE was released less than a year after the Quadro NVS 280, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The Quadro NVS 280 has 64 MB video memory, but the GeForce 6150 LE does not have an entry, so the two GPUs cannot be reliably compared in this area.

The GeForce 6150 LE has 2 Shader Processing Units and the Quadro NVS 280 has 1. However, the actual shader performance of the GeForce 6150 LE is 1 and the actual shader performance of the Quadro NVS 280 is 0. The GeForce 6150 LE having 1 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 6150 LE delivers a marginally smoother and more efficient experience when processing graphical data than the Quadro NVS 280.
