I have a nVidia 7800GT (SLi) XFX GPU Was wondering with the following two that will fit it, Is it worth extra money to go with the "Danger Den NV-78 (Rev1) Water Block" so that it cools the Ram as well as the chip, will this make a difference? or stick with the "Danger Den Acetal Maze 5 Low Profile" for just the chip.
I would stick with the Maze 5 since your not going to see any significant performance increase if any. So long as you put ram sinks on the memory you will be fine. You may be able to increase the memory clock going with the NV 78 block, but I'm sure the price vs performance ratio is not going to be great.
