Video card up upgrade

[Peppered]

I fried my 789 TI my son is letting me use his HD 770 until I can get a another GPU.
I have a I5 4670k at stock speed can't seem to over clock it. I am using a Z87 chip set.
If I got a 980 TI or a R9-furry x would i be bottle-necked bad by my main board and CPU ?

The thing that bothers me about these GPU'S is that keep hearing that next year they should have a single card solution for 4 k monitors ( about time ). So i am hesitate to spend anything at this time if there will be that big of a difference in the GPU's.

I only have a Eiso 144 hz 1080p monitor. Gave my dell 2560 x 1440 p monitor to my wife because she works with photos a lot. A higher res monitor would be nice but the HD 770 would not fair good with it so I thought it better to upgrade the GPU first if it makes sense.

Or should I up date to skylake first then get a better GPU and Monitor later?

I play witcher 3 and witcher 2, tomb raider, and messing with guild wars 2 at this time.

If you swap out your mobo to a z97 you can oc the CPU. There's not much performance gain with skylake outside of igpu performance. Not enough difference when you factor in needing a mobo, CPU, and ddr4 ram vs just a new mobo.

Finding a 290x or 390 for under $250 is a good deal, and a nice hold me over until the new generation of gpus come out and are readily available IMO.

Overclocking should work on that. Have you checked for a BIOS update from your mobo manufacturer lately? Do you have a good CPU cooler?

I haven't tried to OC it after i took the GPU out of the loop, I have on a 240 rad. after the leak i am about done with water cooling that was a expensive card to fail for a small leak. the old old haswel CPU's use to be very hard to over clock i guess I could get a delves canon one and go from there but trying to keep cost low as I can 650 to 700 is all i have to spend.

Forgot to mention this was a 360 and 240 rad.
just want to get the most bang for the buck. wold be nice to see witcher 3 maxed out and at high frame rates. that would take a 980 TI though. and like i said note sure how much those new GPU's will be outdated next year. I am aware that things get out date fast in the GPU market but if they can make a GPU that runs 120 or 144 hz with a single GPU that will be one big improvement.
