hmm, was thinking about water cooling but only the cpu and video cards, dont like the blue at all on the p9's, and dont see how the p9 is better than the r4f, dont need more ram, the only benefit i see the extreme over the formula is the waterblocking. for my motherboard this is what i want, tri sli (quad maybe,christmas time), have 4 slots of ram for my CORSAIR DOMINATOR®GT 16GB, overclock my 3930k to 4.4-4.6ghz. why pay more for the extreme when the formula could do this no problem.
