i agree with the other people in this thread, you should really consider building it yourself
with 3000$ to spend you'd be able to build a BEAST
here's what i suggest

you don't really need an i7 for gaming, an i5 4690k wouldn't be much of a difference.
the titan x would last you a long time and it also has the vram to play games smoothly at 4k later
if you want, you could take 2 gtx 980's and put them in sli, they're as good as 1 titan x but the extra vram would come in handy in the future.
the monitor is extremely good for a single monitor setup and some even argue that its the best you can get. if you want a triple monitor setup, you could go with that too but i wouldn't suggest a dual monitor setup unless you do video editing or if its a workstation pc or something like that.
i'm actually building my first pc soon and i learned a LOT! i'm sure you would too, although if you really hesitant about not building it yourself, i suggest you check out
https://www.cyberpowerpc.com . i haven't used it as i don't live in the US but i have heard good things about it
