1440p 144hz with GTX 970 SLI?

So I bought two EVGA GTX 970s with that MicroCenter price match, and I was wondering if anyone is using a similar setup with a 1440p144 monitor. Particularly, I'd like to be able to run GTA5 at high-max settings without any of the advanced graphics or AA at 60fps, BF4 at 100+ with everything maxed except for AA, AO, and terrain decoration, and CSGO maxed at well above 144fps. Is this realistic or should I try to sell them for a 980ti?
