I'm planning on getting this setup on a DFI board, so how far will Dual Zalman VF700-Cu coolers allow the cards to OC to? At what temps?

I also plan to have a 120mm exhaust fan perpendicular to the cards, sucking the hot air from the zalmans out of the case.

I'm shooting for 450Mhz/1.3Ghz with volt mod if necessary and if the Zalmans can handle the heat..?

Thanks

It's luck of the draw when it comes to overclocking, the same 2 cards can overclock differently.As for the Zalmans you won't be dissapointed

Ya, but will the Zalmans be able to handle the heat in a SLI setup? I mean, in some reviews, the VF700Cu is only 3-4C better than stock cooling on a stock 6800Ultra so I assume that max OC won't be much better...

How far were you able to push your Leadteks with their fancy copper coolers?

I've had a max overclock on the GPU of 465 and it ran the 3dmark05 program without crashing so the Leadteks are all good in my opinion :D

I forgot to add that my overclocks might be because i'm running 2 520 OCZ power supplies, gotta love these CM Stacker cases :D
