Alienware has added the recently launched GTX 660 (OEM-only) graphics card as a choice in its X51 Mini Gaming Desktop, claiming that it should provide twice the performance of the previously available GT 545.
The GTX 660 OEM-only graphics card features a total of 1152 CUDA cores and works at 823MHz base and 888MHz Boost clock. It features either 1.5GB or 3GB of GDDR5 memory (Alienware decided to go for the 1.5GB model) clocked at 5.8GHz and paired up with a 192-bit memory interface. It is no wonder that Alienware decided to squeeze it inside its X51 mini PC as this one is clearly much more impressive than the GT 545 with 144 CUDA cores and 1GB of GDDR5 memory paired up with a 128-bit memory interface.
The GTX 660 adds US $200 to the total price and according to Alienware, it should be enough to give 50+ frames per second in Battlefield 3 at 1080p resolution.
The X51 system with the GTX 660 starts off at US $1049 and you can check them all out here.
