A couple of days ahead of its worldwide launch, NVIDIA's GeForce GTS 450 based graphics cards from various board partners have been listed on American e-tailer Newegg.com. The list of cards shows an interesting mix of prices and variants. To begin with, the base-model (those which stick to NVIDIA's reference clock speeds of 783/1566/900(3600) MHz core/shader/memory, are pegged at US $129.99. These are followed by mild-overclock variants (those with 4~5% increase in clock-speeds) being priced at around $135, those with higher overclock settings out of the box (that's 9% to 12%) are priced between $135 and $140. The GeForce GTS 450 is NVIDIA's lower-mainstream SKU based on the 40 nm GF106 GPU, it has 192 CUDA cores, 1 GB of GDDR5 memory across a 128-bit wide memory interface, and support for the latest PC graphics APIs including DirectX 11 and OpenGL 4. It is slated for early next week.
