For those interested in mining with GTX 750's here is an eBay link to what I am currently purchasing.
https://www.ebay.com/itm/ZOTAC-NVIDIA-GeForce-GTX-750-1-GB-GTX750-1GD5-Video-Card-128bit-DVI-HDMI-VGA/142732559955These GTX 750's are Zotac branded, have the full double wide bracket (easier to attach to mining frames) and can be easily overclocked. I am getting around 245 H/s at 38.5 watts on these.
Another good thing is that these need no additional power cables as they get all their power from the PCIe slot. With the power draw being so low you can use risers that are powered with SATA to 6-pin cables.
