The GTX 660 seems to be an interesting card. The Hawk edition from MSI should allow us to really push it on LN2 too!
MSI's upcoming GeForce GTX 660 Ti HAWK 3 GB graphics card, installed in 3-way SLI configuration was pictured. One of the three was put through 3DMark03 and 3DMark 11. The picture reveals a card that looks similar to the company's GeForce GTX 670 Power Edition. MSI used double the memory amount, by populating the GPU's 192-bit wide GDDR5 memory interface with 3 GB of memory (2 Gbit x 12). The card is cooled by MSI's Twin Frozr IV cooling solution. It is clocked at 1020 MHz GPU core, 1098 MHz GPU Boost, and 6.00 GHz (GDDR5-effective) memory. The GPU-Z screenshot reveals more details.
While three of these cards were pictured in 3-way SLI configuration, only one of the three were put through tests. The cards were driven by a yet-unannounced GeForce 304.87 beta driver. In 3DMark03, the MSI GeForce GTX 660 Ti HAWK scored 18,731 points, and in 3DMark 11 Extreme Preset, it scored X2,862 points. Both these figures are similar to those of a reference NVIDIA GeForce GTX 670.
