I'm still rocking a 5670 and I've been wondering if it's time for an upgrade. I don't really play graphic intense games, mostly Indie stuff like Cave story and Binding of Isaac. Would it still be worth it? If so what's a significant upgrade from such an old card?
If you seriously play only those games then no. Although, a 7850 isn't expensive and would be a nice cheap upgrade. It really depends on what you NEED to play / max / whatever.Only you will know the answer to that.
