The X600 to 6800Go worked because they are both cool running cards

. What is the video card cooling solution on the M70? Is it the same as the D810? I can tell you right now that the Go 7800GTX WILL NOT work in a D810/M70. It's power requirements are too high, the BIOS doesn't support it, and the cooling solution can't handle the heat that comes off the card. However, depending on how cool running the new 7800 Go is, you might be able to get one of those in there
