Guys from Expreview.com managed to find a picture of the alleged Geforce GTS 450 PCB that was published at PCinlife forum and which shows at least some details regarding the upcoming GF106 based card.

Unlike the GF104, it looks like the GF106 is a square chip and the PCB also shows a six memory chip configuration as well as the 3+1-phase power design. Bear in mind that there has already been rumours that partners will be able to make their own cards from day one. Other noted features include a single 6-pin PCI-E power connector, single SLI connector.

It is still unclear if the PCB is the actual Geforce GTS 450 or some other card based on the same GPU, as there was rumours that the GTS 450 might come with 1GB of GDDR5 memory. The backside features two DVI and mini-HDMI outputs.
