I would absolutely not buy a "new" GTX 750ti if it's at that price as there are a ton of dodgy GPUs being sold as new for bargain basement prices on eBay. Like the one pictured in the link above is quite obviously fake, looking not even remotely like a 750ti PCB, has an SLI connector (the 750tis do not), and most of the specs being suspiciously off for a 750ti.
