There was a big to-do yesterday with the release of the GeForce 9800 GX2, the dual-GPU supercard from Nvidia. Reviews were cautiously positive, but Bit-Tech had a mysterious problem: constant overheating.

They did some testing and found that on some nForce 700 mobos (in their tests, the Asus Striker II), the placement of the nForce 200 chip made for a hot pocket of up to almost 200 degrees Fahrenheit/90 Celsius. The card itself has a higher tolerance than the mobo and the entire system was shutting down because of this design flaw. So, before you lay down that $600 for a GX2, check your motherboard and see if the placement of the chip is going to be a problem. See the illustration above or the link for more information.
