Here are the minimum and recommended specs for
Bioware's people are almost as hardware-ignorant as Bethesda's seem to be. With regard to their announced video graphics card requirements, the two minimum cards are in conflict presently (as to how they would benchmark).
The Geforce 7900 GS is a five year old card roughly equivalent to the Radeon X1800 Pro, or the four year old HD 2600
XT cards. It is a lot faster than the Radeon HD 2600 Pro, but it also has much poorer image quality and a far less effective shader capability. The Geforce 7800 GS is much closer in speed to the HD 2600 Pro. Personally, I think that they should have named the Geforce 8600 GTS, and forgot all about the Geforce 7n00 generation, just the way they seemed to want to omit the Radeon X1n00 generation.
