The XFX card is based upon NVIDIA's GeForce GTX 275 chip. This chip has 1.4 Billion transistors and is manufactured under TSMC's 55nm process node. It has the same number of Processor cores as the high end GeForce GTX 285 but with the memory controller of the more mainstream GeForce GTX 260 216 core (i.e. 448-bit). This is actually the same chip used in a dual chip configuration called the GTX 295.
The main features of the card include full support for DirectX 10.0, PhysX, CUDA, PureVideo, OpenGL 3.0, and SLI. DirectX 10.0 was released along with Microsoft's Windows Vista Operating System and includes Pixel Shader 4.0, Vertex Shader 4.0 and most games released for the PC platform support features of the API to improve visuals. Games like Crysis, Tom Clancy's HAWX, and many others use DirectX 10.0 features to show off beautiful water, vegetation and more.
NVIDIA bought Ageia over a year ago and has now implemented PhysX support on all of their video cards from the GeForce 8 generation and newer. Games like Mirror's Edge, Terminator Salvation, Two Worlds and many other released and upcoming games. PhysX allows the developer to include physics effects including smoke, fog, destructible terrain and realistic weather effects in their game at a minimal CPU hit. Scalable Link Interface or SLI was introduced by NVIDIA in 2004 with the launch of the nForce 4 SLI series of chipsets. Today SLI is the most used multiple graphics card solution on the market according to Steam. To use SLI you need a compatible motherboard (nForce 790i SLI, Intel X58 chipset etc.), two of the same kind of video card (GeForce GTX 275) and the latest Forceware drivers to enable it. The new X58 chipset will also support SLI.
