well there are smaller jumps then liquid nitrogen. Lets wait and see what can be done with water and compressor before you say you need liquid nitrogen. And dont give up on air yet, there are many options of air coolers out there to be tested. Ill wait tilll we see mroe overclocking reviews before making my decision, just becuase reviews taht dont usually cover heavy overclcoking did and didnt come up with big results, doesnt mean its a no go. Personally I wasnt expecting some big revoltion with the fx-53, Im waiting to see the 939 transition to see how the cg revision can really perform, or not perform. This piece is mearly to keep the compitition up against the p4ee , although i dont see the reason, there isnta huge demand for p4ee's. Its fine for what its sold at, the performance at stock speed is fine. Ill wait to see some more in depth overclocking reviews.
