Would an upgrade in GPU have a big impact on VR performance?

Hi, i'm using an AMD r9 290 with an oculus rift and for the main part it handles the games fine, the steamvr ready checker considers the platform to be in the green 'ready' section and I've not had any noticeable consistent tearing/stuttering. However I do find wearing the headset for more than 30 minutes to be pretty nauseating to the point that I rarely use it. I'm wondering if upgrading the graphics card would have a significant impact to the way the games feel. Does anyone have any experience of upgrading their card and the difference it made to the vr games? I'm worried I'm gonna fork out best part of £500 for a 2070 just to find the games acting very similar without any significant difference.

Cheers for the reply's, Its interesting to know having a superior card doesn't appear to effect the vr experience vastly, though I will check the fps I'm getting in game and see what level its performing at atm
