Can't see the price on the 760 but I'd definitely recommend it over a 270X if the price difference is nominal. The 270X comes close in some games but it's not quite the solid mid range performer the 760 is. Going back to my earlier post, I'd recommend this much more over both of them:

It's an EVGA GTX 960 for $180 after rebate. That's only $20 more than the lowest price for the 270X (which is sold out anyway) and it comes bundled with a sexy backplate and a free code for Metal Gear Solid V when it comes out next month. EVGA also has a reputation for making some of the highest quality computer components today. I used them for my power supply and they're widely considered the premier manufacturer for Nvidia graphics cards. This is a card that will last you the entirety of the console generation and run games considerably better than the PS4.

One last piece of advice, it's good to Google comparisons of two cards and check out what sites like GPU Boss have to say. Just make sure you compare the game benchmarks because those are the only numbers that matter, a lot of the other categories don't have the final say on performance.
