For most graphic cards it doesn't matter, most cards are profitable on ETH mining and few like Rx Vega 56 and 64 are profitable for ergo mining, the 3070ti are good for ravencoin and TON coin so there you have it, all this depends on the cards you own
The question is interesting for me because l have a few older cards like 1050Ti and they can only mine Raven
Today I can mine with them more or less profitable but I'm wondering what will happen after the halving
Ravencoin mining reward will become lower so it will be more harder to mine ravencoin, we have TON though have you checked that out? I'm not sure that 4gb cards works with this coin but it's still new so try checking this out first
