That's a 950 in there right now, so most likely if your 750 Ti of choice is of the smaller variety, it will work.

First of all -- it likely won't work. 750ti and any maxwell card need to have a UEFI BIOS.

Second of all, your power supply _probably_ isn't powerful enough.

Update your BIOS before you buy it, and then even then get it from some place you can make a return to ez. Price match with Best Buy or Microcenter, preferably.

My Dell XPS 420 with no UEFI runs a GTX 950 just fine.
The 750 Ti uses approx. 60 watts, so it is possible that OP's psu is enough.
However, on my computer, a latch that closes on the top of the pcie bracket cannot close due to the height of the 950. Considering that I don't see a latch near that area, OP might have to saw that part off to fit a dual width card. With the crappie picture though I can't really tell.
