Since budgets keep climbing and sales stay the same, it makes sense to stop at some point. Games like Minecraft, WoW and every indie game ever show that people care more about art design and gameplay than they do pure tech. I am definitely at a place now where I don't need graphics to look any better.
How about you? Eager for new consoles, hoping graphics take another leap? Looking to SLI two amazing new video cards this Fall so you can pump out the latest amazingness? Or are you good to go, like me, and hoping for a very small upgrade?
