I am planning to get a video card to mine litecoins in 1 month. I don't know if I should get a 7870 or the new R9 270x. The R9 is basically a re-brand of a RHD 7870, so I would expect it to have the same hash rate. However,
https://litecoin.info/Mining_hardware_comparison. .says that a R9 270x gets 475 Kh/s (1120 MHz), and a 7870 (1120 MHz) gets 385 Kh/s.
So which one is better? On Newegg, a Radeon 7870 is $150, and a 270x is $200.
