Galaxy GeForce GTX 760 GC Edition 4GB Video Card with Free Splinter Cell Black Game.
May not be the best brand, but consider the cheapest among all the other brand GTX 760 4gb.
If you doesn't like NVIDIA and prefer AMD, here's a cheap HD7950 to be grab too.
Good price. Here's how it compares to the $269 7950 from that other deal today:

Bit faster on some games, bit slower on others.
Tom's puts 760 and 7950 neck-and-neck, but if you need any of Nvidia's special features (slightly better stereoscopic support, CUDA), $30 is not a lot more to pay, I guess.
