Questions on my cooling config for Radeon 9700pro

[XxPrOdiGyxX]

Ok...out of all the forums I read I think the ones here are the most knowledgeable so any help would be appreciated. I was trying to get the Zalman ZM80 heatpipe but I accidentally ordered the ZM50. The site I ordered from is being gay and would not change my order when I notified them well within the first hour after the order was made. But that is a separate issue. Anyhow, instead of paying a bunch of shipping fees to send it back and have the right one sent I'm thinking of sticking with the ZM50. In the specs it says to use ZM80 instead of ZM50 for Radeons faster than the 7XXX series. Is this really going to be a problem? Or will the heatsink still cool my 9700pro enough? I'm also adding the OCZ bga ramsinks as well to maybe help get more cooling done.
