Even I couldn't find any online store with the Big Bang haha.
My Suggestion - Yes, the Big Bang looks great but I recommend you get the Asus Maximus V Formula instead - Better audio, better OC capability, much more gaming oriented, wins in benchmarks. - Yes I've already compared it haha.
The Extreme/Formula beats the Big Bang in benches.
Thanks arzbhatia, I'll go check it out...Liked the yellow/black thing though, matched my guitar but I would rather spend the money on performance than color. I could buy the ASRock Z77 OC Formula but it a CEB board and I dont think it will fit the DIYPC Alpha-GT3 tech station Im getting.
