Honda...you are a really good overclocker and lucky guy too... lol
In my big country (Brazil), we just have Artic Silver 5 and ceramique...LN2 about 6~7 USD per liter and LN2 impossible at weekends
I have only 15 lts Ln2 and no good thermal to test (used mixed OCZ freeze + Ceramique when i got 1530 Mhz).
Does anybody knows about "Liquid Pro" to extreme (VGA)???....
My friend told me can give me one to test a lit bit more....but almost sure I am out MOA this year.
