I'd say it still is. depending on the game, you still might be able to pull off high settings... most games probably medium to low... more demanding ones will be on low.
I was getting decent performance with a 955BE overclocked to 3.7 (no voltage adjustments) on regular HSF and sporting a HD5870 (1GB)... upgraded to something more potent in CPU (i7-5820k) though, and something a bit more potent in the GPU department (R9-380X) If I can scrape up some cash, Vega sounds like something to move to if it isn't too expensive.
