The new GeFroce GTX 260 from Galaxy features a custom cooling solution, with a large aluminum heatsink and four heatpipes. The cooler manages to keep the temperature of the card at 67°C during a round of FurMark testing. The site also mentions the great overclocking of the card, they say you can push the core to 750MHz and the memory to 2600MHz.
The non-reference 55nm GeForce GTX 260 shares the same PCB design with reference GTX 260, without shrinks on specifications. Equipped with Samsung 1.0ns DRAM, Galaxy 55nm GeForce GTX260 is coming with 896MB/448bit and default clock of 625/1350/2100MHz, up from 576/1242/1998MHz on reference card.
