I'm thankful for all of the feedback here, but just want to give a special note of thanks to Unstable for the example builds.
In that $1,000 build (for the PC), Unstable listed this graphics card: EVGA GeForce GTX 970 4GB Video Card
Is there any website where I can punch in a graphics card and see examples of how different games perform using that graphics card?
Again, I apologize if I'm not asking the right questions. Not an expert by any means!
I'd recommend just reading various GTX 970 reviews to get a rough idea. The test computers they use do have very expensive CPUs, but that's just to make sure the CPU isn't a limiting factor.
