Which one to buy

Choose the Radeon R9 370 if you want the faster card, and it also has at least as much memory. It makes the most sense at 1440p and above, or on a monitor with a high refresh rate.

Choose the Radeon R9 270 if the price gap matters more than the 5% speed difference. Whichever you pick, check reviews for the games you play, because two cards with similar scores can differ in individual titles.
