So I recently saw some dell 780Ms for sale on Ebay and I saw 2 different ones, one with the X bracket which was like %100 more expensive and one without it. I'm just wondering if I were to upgrade my old 680Ms in my m18x r2, will i need new X brackets or can i just use the ones on my 680m? Also, will the heatsinks for 680m work with the 780m?

so im using the dell 680m 1000v revised vbios and apparently it makes my sli gpu usage throttle like crazy when there seems to be a lot of stuff going on on the screen in crysis 3, bf3, and a lot of other games. overclocking seems to make it worse. when there are no AI on screen i get a steady 95-97% usage on both cards but as soon as the screen begins to fill up with AI, it drops to 50%-40% per card and i get horrible fps...btw i got a 3940xm OC to 4.3ghz so idk if it could be a cpu bottleneck. just wondering if anyone else is experiencing the same thing.

On the Dell 680m - 80.04.33.00.32__'OCedition'_revised_00 - OV 1025v.zip i am only able to OC the core clock to 810 max with nvidia inspector and it seems it wont go higher...im just wondering how you all are able to clock higher...
