For last few days there was a rumor of nvidia releasing new Geforce GTX 560Ti with 448 cores inside.
Well today rumor become true...........
NVIDIA released its newest graphics card model specifically for this shopping season, the limited edition GeForce GTX 560 Ti 448 cores.
The new card is based on the 40 nanometer GF110 GPU (which is used inside GTX 570/580) instead of the GF114 that the regular GTX 560 Ti is based on.
This allows NVIDIA to add 64 more CUDA cores (448 vs. 384), 25% more memory (1280 MB vs. 1024), and a 25% wider memory bus (320 bit vs. 256).
ZOTAC, ASUS, Gigabyte, and MSI will have graphics cards based on this chip. Prices should typically start at US $289 for reference model.
