THG has another big round up of video cards on the plate this morning. They're comparing three 7800GTX's, two 7800GT's, & two 6600GT's both on their own, & in SLi. Not a bad 43 page summary...

"We put the THG screws to seven of NVIDIA's new graphics cards, ranging from the GeForce 6600 GT to the GeForce 7800 GTX with 512 MB of video memory. Power consumption, heat dissipation, noise level and, of course, overclocking potential are detailed."
