an i5 is kinda slow for the gpu , if I was you I would upgrade to a i7 processor , you would be definitely bottlenecking the pc you processor will be too slow , I have a i7 4790 processor and its running alittle slow and i'm using a gtx 1080
That is completely bs. An i7 is in no way needed for gaming, and very rarely preferable to an i5. Very few games are going to use the additional cores in a real and meaningful way if at all. For almost all of gaming buying an equal power i7 instead of the equivalent i5 will gain you nothing, you're just throwing away money. Increasing the power of the chip will absolutely help your gaming, to a point, but overclocking is by far the most cost effective and simple way to do that.
Overclocking is extremely quick and easy these days. Installing an aftermarket fan like the Evo 212 isn't really any more difficult than installing the stock fan included with most CPUs. A few extra screws is all it takes to make sure you're running cool. For instance, the stock fan with the 4690k is garbage in general, but pop on a $20-30 aftermarket fan and you're set for overclocking. With a $20-30 investment in a nicer fan the 4690k is very easily stable at 4.4Ghz, many going higher. If you don't want to take the time to really learn the ins and outs of overclocking most motherboard manufacturers now include some type of automatic overclock settings in BIOS. These used to be a pretty poor choice, but in the last few years they've gotten fairly decent.
An Asrock z97 Pro4 is far from a top of the line motherboard, but paired with a 4690K all you have to do is click on the 4.4ghz overclock setting in BIOS and it will take care of it for you. You'll be using a bit higher vcore power than you likely need, sure, but the setting is safe, instant, and effortless. If you don't want to really mess with overclocking you can use this method to get a 900Mhz boost for $20-30, 30 minutes to swap cpu fans, and about one minute to boot to BIOS and change the setting.
If you'd like to take the time to learn more about overclocking and tinkering you can gain more, yes, but often not a lot more than can be done automatically with the mfg BIOS settings. After 5 hours of tests and tinkering I found that my 4690K tops at 4.7Ghz. Yes, it's a 1.2Ghz increase over stock, but only a 300Mhz increase over the automatic BIOS OC. It's a relatively cmall boost compared to what Asrock (and other mfg) let you set and take care of automatically.
Bottlenecking - There is no consumer video card on the market that will be bottlenecked by an i5-4690 at stock much less overclocked. You can run SLI 1080s on a 4690k and the CPU will not bottleneck the cards.
