New $1000-$1200 Build - Requesting Advice

For your low resolution monitor you should be looking at a GTX 950.

For your budget a GTX970 and a decent 1080p monitor

Well a few things. For starters, you should get a better psu. Even if you don't agree with the rest of the parts in my suggested build, EVGA's G2 series is a lot better than its B1 series, so get one of those. I'd also get a different case because I've heard that the 200R has heat problems with its drive bays for some reason. As for the game performance of your build, it would be able to max out any new title at 1080p and keep a constant 60fps. But don't expect it to play Ark: Survival Evolved. That game runs horribly on most rigs. I have two gtx 970s and an i5 4690k and I sometimes hit 60fps at the lowest settings at 1080p. That's unacceptable performance, do NOT buy that game. But anyways, I'd suggest this build instead. Just so you know, this build can not overclock, but if you overclocked the processor from your original build a decent amount, it would be about the same performance as this build. I'm not certain about that, but you wouldn't need to upgrade this processor for another 5 years easily, so don't be afraid to buy a processor taht can't overclock. And by the way, your original build wouldn't be able to overclock either, that would require a Z97 board I think. I could be wrong about that last part, but I'd look it up before making a purchase like that.

Edit: So yeah basically I agree with Blackbird on all of the points he made, and he's definitely right there's no way that $20 windows key is legit.

Latest hardware , decent monitor and an appropriate sized one for decent gaming
