Msi Hd 7970 Lightning.

Sapphire Vapor-X 7970 GHz. Runs up to 1.3 V on the core. Doesn't guarantee a high overclock and only runs with Trixx though.

Any reference models with the reference cooler will allow voltage control.

The 7970 will for sure, and unlike reference cards it comes with nifty little things you plug in and attach to your multimeter to get ACTUAL voltage readouts (GPU Core, VRAM, and I forget the third?), very useful. The stock cooler is also very very good, but if you want to push some REAL volts, I'd highly recommend water (regardless of the card you go with).

Be VERY wary of the EK 7970 Lightning blocks... Some serious QC issues, and I've seen them kill a few cards (100% NOT installation error; the blocks are just junk).
