$150 seems to be more likely for a 750Ti which has the new GPU architecture. If you got a 780Ti for that price please give us the seller. I think they tend to be more in the $600+ range.

Never had a problem with 5 or 6 from 4 different locations.

I have a EVGA GTX 750 Ti 2GB Half size card, no additional power required and uses the latest chip set. So far seems to work well and price is good. Here is a review of the chipset.

You need to be sure of a couple of items when buying a card in addition to the chip vendor. The 780 is a dual slot full length card and depending on where your PCIe slot is you might not have the room to fit it in. Also, you really want to install it in a PCIe 3.0 16x slot for best perfromance. Finally, it requires a lot of power from th power supply so you need to be sure; 1 - that your PS is big enough to support it (most likely 600 + W PS) and that you have a connector from the PS for the card.
