The Ranking for nVIDIA cards goes as follows:
Ref: http://en.wikipedia.org/wiki/GeForce
- G or GS - The standard video cards with core clocks that are not high and are made to keep a minimum performance.
- GT - Slightly higher core clocks and possibly more onboard memory than the GT, It is mainly a budget performance card.
- GTS - Includes possibly more onboard ram and higher than average core clocks possibly more pixel shaders or pipelines to increase performance.
- GTX - Has the most memory of the group and higher clocks than all previous also includes more pixel pipelines and usually outperforms the GTS by atleast 10 - 15 percent.
