Here's why.
2 years ago i was building a new rig, asked everybody for what gpu should i go with for my budget and the resolution that i'm content using with (which is 1440x900). At that time, ever single person that i've asked for advice that, is GTX 670 will be future proof for my resolution at 900p for at least 4 years on ultra settings, folks said that a GTX 670 will be "overkill" for that resolution and i should get a gpu like 7850, which i ended up getting.
Once i finally built my system and using it with intense games like Metro 2033, Last Light and many more, i saw that it was not true at all, even a 7850 couldn't handle games at maxed settings on that resolution.
Anyway, i'm going to upgrade my GPU and was wondering should i get something like GTX 970 or going with something higher ?
I'll be using it with 1440x900.
So, here's the rest of my system at the moment.
