no such simple rule with ATI, just get a card with at least 256 bit Memory Interface and 2 GB Ram.
Decent graphic cards from ATI:
256 Bit Memory Interface:
R9 270 2 GB Ram
R9 270x 2 GB Ram
384 Bit Memory Interface:
R9 280 3 GB Ram
R9 280x 3 GB Ram
The X version have a higher clockrate, but that's not realy a reason to spend more money.
Even the R9 270 is fast enough for MWO, the R9 280 is even fast enough for Battlefield 4 (both in 1920 x 1200 px).
Some R9 270 have 4 GB Ram, but that offers no benefit and is wasted money.
