Hi Folks, Pondering options for a boost from dual 2.26 in my 4,1 and was wondering what the wisdom of the interwebs is regarding a pair of the 3.33ghz W5590 (used lidless). Pros as far as I can see - faster clock speed, a lot cheaper than twin 6 core chips (cheap enough that stuffing up a delidding isn't the end of the world if I have to DIY that), and utilises 1333mhz RAM without a 5,1 firmware upgrade, so keeps the machine more "stock". Cons - Hotter? Uses more power (to do the same task or has more headroom to use more power doing more tasks)? Finding a tutorial on applying thermal paste to a lidless CPU? thoughts?
