Nvidia GeForce GTS 240

Meet the G92, the most rebranded chip like... ever.

This new card is nothing more than a slightly revamped 9800GT with a new PCB and G92b chips exclusively:

Based on 55nm G92 chip, the GTS 240 OEM features 112 stream processors, 1GB of GDDR3 memory, and core/shader/memory clock of 675/1620/1100MHz

This "new" Nvidia GeForce GTS 240 card has improved clocks, very similar to the original ones of the 9800GTX. The extra memory is an interesting addition and a similar step taken with the GTS 250, which put more emphasis in the 1GB variants than on previous generations. The extra framebuffer won't deliver higher maximum framerates but will help them not go so low in some heavy load situations, a situation that has started to occur in more demanding games.
The PCB has been revamped and although it is certainly a cheaper design, it does not seem a low quality build. The inductor in the bottom right corner is the only thing that seems cheap but as long as not much power goes through there, there won't be much electrical noise.
The card is OEM only for now and retail availability in the future is still a question. One can always grab the 9800GT, albeit with the slightly lower clocks. 1GB versions of the 9800GT are selling for around $140 or 110eur.
