Nvidia is going to be releasing some new cards very soon and their GK110 cards should come down in price a bit so if you could wait for that you may save some money. Just read they are releasing a GTX-750Ti very soon now.
MSI just came out with their 780 Lightning card that is faster than a stock Titan out of the box with no over clocking. It looks like hell of a card the way it is put together, massive power and cooling. 980/1033 MHz clocks and 16+3+1 Phase power design, TriFrozr cooler, there are two 90mm fans on the sides, with the one measured at 80mm in the middle, back plate, front plate. It is a beast in all respects. May want to take a look at this one.
