Basically, my current setup consists of a Gigabyte X58-ud5 motherboard, i7-920 processor, Corsair H70 cooler, and 4 modules of G.Skill RipJaw RAM.  
I was thinking of switching coolers from Corsair H70 to Noctua NH-D14.  I have plenty of room in my case.  
1.  Does anyone know if this behemoth of a cooler would block anything... ram slots, pci slots, etc. on my board?  If anyone has this setup and has a picture, that would be great!  
2.  Also, would this cooler switch be worthwhile or would I be wasting my money?  Yes, it's overclocked and my temps currently are 76 C.
THANKS!!
