Will i need extra fans?

Will i need extra fans for my new build if i buy the over clocked edition of the sapphire hd 7770? i will only be using the case fans, stock fan for the cpu and the gpu fan

all modern generation gpus run pretty cool at factor clocks generally. unless you live in a really hot area, you dont need extra fans(but would be preferred to have a decent fan setup going on)

My OC'ed 6850 (probably runs hotter than your newer 7770) never goes above 75c at 100% (furmark). I run 2x120mm 75cfm intakes and 2x120mm 75cfm exhaust fans. It's probably overkill but I'd rather be safe (and loud) than sorry.

my case fans make no difference in temps. maybe 1c. and i have 3 GT 1850rpms

It really depends on what kind of a case you have. Some give better cooling performance if you add more fans in certain spots, others have minimal effects.

well my case is the 550D which is a hothouse according to most reviews.
