Update: @Alex: I was told 8 had a simpler interface and is faster compared to 7 and also i need a change!

Will it perform better with 8? because note that i have mediocre specs and i want it to be performing the best it can.

If it was just down to performance, with my specs, Win 8 or Win 7?
Update 2: wow! such rave reviews!
Update 3: @Alex

Update 4: PERFORMANCE WISE, GUYS!!
WIN 7 OR WIN 8!!???
