Hexus has brought us word that both GeCube and Sparkle are going to be using thermoelectric cooling (TEC) solutions for some of their future graphics cards. GeCube will be using TEC on a new overclocked HD 2900 XT and Sparkle will use it for their Calibre P880 and P880+. I am pretty sure the P880 is a 8800 GTS and the P880+ is the 8800 GTX. If you are wodering what TEC is, please check out the TEC Wikipedia page.
Hexus was able to obtain some more details on the GeCube Gemini. At least some of those 4 DVI ports are dual link, but Hexus did not say if they were all dual link.
