According to screenshots posted at China Daily (Translated), it looks like Nvidia is getting ready to release a new midrange graphics card to sit under the GeForce GTX 760 (a spot currently held by the ~$250-300 GeForce GTX 660 Ti). It is detected as the GeForce GTX 750 Ti and 760 SE, but we have seen this before. Most likely it will be named the 750 Ti.
The GeForce 750 Ti is said to have 32 ROPs, 80 TMUs, a “11C7″ core running at 1033MHz base with 1098MHz boost, and 2GB of GDDR5 memory clocked at 1502 MHz on a 256-bit memory bus.
According to the site, we should expect to see it to be announced in early October, or perhaps late September.
