Aye! U R right . Cooling the vram is not pressing isue it mostly stand for 1300Mhz EZ without cooling. I have not checked but i sore they had some reference standard up to that XXX it must work stable. The pressing issue is the GPU cooling m17x GPU cooling is relatively not bad but is lack of proper design. Since the highest gpu is 5870 for m17x dell had no interest to do anything. R3 housing a single 6970M performs similar than 2 5870 not really point to go for single.
