"As well, Nvidia has released OEM budget/mainstream cards under the GT100 series as well, with similar naming schemes to the mobile cards. Current cards include the GT100, GT120, GT130 and GTS150. The GT120 is a rebranded 9500GT with improved thermal designs while the GT130 is a modified version of the 9600 GSO. The GTS 150 is an OEM version of the GTS 250 with some slight changes."
The whole rebranding idea on the part of nvidia does make sense on some levels, it's got alot of pros and cons, for the consumer it's alot easier to compare cards when they go up in logical steps, it's pretty obvious that a 280 is better than a 260 and a 260 is better than a 250, however and consumer wanting to upgrade their computer to these kind of cards are going to be at the very least mild gamers, which means that they are going to have some knowledge of gaming cards, thus know that a 260 is better than a 9800GT.
Those that don't know much about computers and technology but play games are more likely to buy a console than a gaming PC.
This rebranding of existing cards with no substantial benefits must be costing nVidia quite a bit I reckon, and on the surface it sounds an insult to it's consumers bringing out 'new' cards which are not new.
