Hey guys been reading a thread here and one guy said:

"I'm using a Swiftech MCW60 block with G80 adapter "

Now I am worried. What is a G80 adaptor? Do I need one?
The GPU block I got says:

1. Pre-assembled retention mechanism using the four holes surrounding the processor:

All nVidia® GeForce™ series from 6800 and above
All ATI® Radeon™ series from X1300 and above

I assumed that it will work with 8800GTX. If it does work why are people running this GPU block with a G80 adaptor? (btw the reseller that I got this from does not sell any G80 adaptors or any adaptors for the MCW60 block so I hope I dont need one as sourcing one will slow down my build)
