Well there is always a bottleneck, with a 8600k and 1080 your bottleneck would be the 1080 in pretty much every game at say 1080p+.

An 8600k and a 1080 is a good combo, there should be no CPU bottlenecking. You can look at the 1070 ti as well should be cheaper if you can find one and performs pretty much the same as the 1080.

How much are you looking to spend on a mobo? This is probably the cheapest Z370 board I would recommend.

thanks for your advice :) with the 1080 being the bottleneck, do you think ill still be able to play games at 1080p-1440p okay? sucks that the 1080ti is about $400 more expensive ($1200 AUD) and do you think its worth getting the 1070ti over the 1080 when most video comparisons say you get the same experience when you overclock (which I don't know a lot about/how to do (I'm sure i can learn pretty easily) when its about $50-$70 cheaper and maybe having to overclock on every game(which i don't know if its gonna be bad for my pc in the long run, sorry I'm still abit of a noob in that department) also I've looked at motherboards and your right z370 is probably the best option, this is the one I've found so far https://pcpartpicker.com/product/rXCrxr/msi-z370-gaming-plus-atx-lga1151-motherboard-z370-gaming-plus tell me what you think, thanks again :)

Yes, any gamer would want the GPU to be the bottleneck ideally. If you got a 1080 ti it would be the bottleneck in that sytem for most games as well.

A 1080 or 1070 ti do pretty well at 1440p. I would certainly get a 1070 ti over the 1080. It is very easy to overclock a GPU nowadays, plenty of good guides out there. Overclocking in and of itself wont decrease the lifespan of your components at all, heat and excessive voltage does. And since pascel cards are voltage locked, neither heat nor voltage should be a problem when overclocking pascel cards assuming you get a decent card not one with some awful cooler.

As far as I know Z370 is the only option as of right now, I don't believe intel has released any other chipsets for coffee lake yet. And it is the only option if you want to run memory speeds over 2400mhz and overclock your unlocked k CPU.

I don't generally recommend the cheaper MSI motherboards. From PCB analysis's I have read they tend to use quite low end cheap components for things like power delivery for the CPU and RAM. But go for it if you want, it will likely be fine especially if you plan to keep the CPU at it's stock clocks.

hey sorry for the late reply was bit late here when i had replied last but ill give you a couple links to sites to look at that will have a good range of motherboards and gpus that we have available here and would you be able tell me what you think will be the best motherboard for overclocking the cpu and the best gpu for overclocking (fans etc) would be muchly appreciated :) you can add some others that they don't have on the websites from pcpartpicker etc cause I'm sure ill be able to find one just but ill link these anyway, thanks :) (I've decided to go with the 1070ti btw) price range/budget for the motherboard is around 200-300AUD also I'm not stressed about the price for the 1070ti cause the prices are all around the same range

As jayz2cents would say "that's not a bottleneck, the 1080 will be fully utilized, just not providing as many frames as a more powerful cpu like an 8700K could provide." A bottleneck would be if you paired it with an old school Core 2 Duo or Core 2 Quad where gpu usage would probably be in the 30% range. But an i5 8600K would definitely not bottleneck it at all, because the 1080 should still be used 100% unless you plan on playing at 720p and maybe 1080p but 1080p would be a stretch.

what are thoughts on the performance for 1080p-1440p? because the i7 8700K is about $200 more expensive here, also what do you mean 1080p will be a stretch btw? for 100% usage I'm assuming? an upgrade from the the i5 8600k to i7 8700l is about $200 price difference like i said and from the 1070ti or 1080 to the 1080ti is about $400 (AUD)

I mean it would perform fine it really all comes down to the game, It definitely will not bottleneck under any circumstances. But in cases where games use as many of your threads as you have it may be 10%-15% slower at most (realistically 5%) than an 8700K. Is 5% worth $200 more dollars is up to you. Needless to say It will still use the gpu to its fullest potential no matter what unless the game is a really bad pc port that just eats any cpu alive.

yeah i probably won't bother with the i7 8700k, thanks for the insight :) question thats abit off topic but what power supply wattage would you recommend for overclocking the cpu and gpu(1070ti) would 650 be enough or too much?

The 1070 ti strix is a very good GPU I would recommend it. The ASUS strix Z370H is a good choice for mobo too, I am actually using a ASUS Strix Z270F and I think it is a great motherboard, very intuitive bios, no issues with it at all.

What power supply? Get a decent one. 650watts is plenty, 550watts would be more than enough as well.

As for RAM, I would get something on the Strix Z370H's compatibility list. That board will support very fast memory so it depends on what you want to spend. You start seeing diminishing returns over say 3200mhz, RAM faster than that starts to get quite expensive and doesn't generally help performance all that much. I personally use a GSKILL Trident Z 3200mhz CL15 kit and am very happy with it.

would you recommend 600w-650w keeping in mind ill be over clocking a lot? and what do you think of this motherboard theirs been some good word about it? https://www.umart.com.au/ASRock-Z370-EXTREME4-LGA-1151-Motherboard_40518G.html the z370 i linked you had some mixed reviews but they may have fixed them by now

14 phase VRM, 12 for CPU, 2 for memory it looks like. Which is probably overkill, so that's good. Long list of features. ASROCK's BIOS has gotten a lot better, but still not quite as good as ASUS's if you ask me. In terms of power delivery it's probably better than the strix. All professinal reviews are good. Yeah it looks like a very good board.

PCPartpicker doesn't have a lot of options but here are a couple I could find.

Excellent PSU reviewed very well: https://au.pcpartpicker.com/product/Rp8H99/corsair-power-supply-cp9020091na

Cheaper but still high quality: https://au.pcpartpicker.com/product/PVzZxr/corsair-txm-gold-650w-80-gold-certified-semi-modular-atx-power-supply-cp-9020132-na

just saw that you replied about the second board then my bad asking twice but sweet, i have two pretty good options to go with, and thanks for the advice concerning the ram aswell ill have to have a look into the trident and see what prices i can find them at :) only thing i can't figure out now is do you think 650w will be overkill considering ill be overclocking every game? or do i go with a 600w to be on the safe side?

would you recommend it over the strix or are they both pretty similar in performance? and as in with the overkill you think its a good choice? thanks for bearing with me with all this btw you've honestly helped me out a lot :)

Either really, I like the ASUS board for it's BIOS and ASUS is useally very good with software and updates. For example they were the first mobo manufacturer to release BIOS updates for the recent spectre and meltdown exploits. But in terms of the VRM that Asrock board is quite nice.

Nothing wrong with going with a slightly overkill PSU. 650watts is a good match for that system. However 550watts would be enough for that sytem with an overclock.

yeah i would rather the easier to get around bios and earlier updates but i had a look into reviews and from what i remember with the asus board they said the vrm heatsinks weren't very good so idk if thats gonna be bad with me overclocking all the time, had a look a the g skill trident rgb and man they look nice i want them so bad but from looking around i can't see any compatibility with the asrock motherboard :( I've found this ram which is probably complete overkill but I'm guessing i wouldnt have to upgrade for a long time? https://www.newegg.com/global/au/Product/Product.aspx?Item=N82E16820232445&cm_re=g_skill_370z-_-20-232-445-_-Product only reason I'm thinking is its a little bit cheaper than the 3866mhz and 3733mhz (I'm assuming because most motherboards don't support such high mhz ram) and its only $26 more that the 3600mhz, what would be your advice on that and the ram itself as in quality? was literally about to order the parts tonight but had one last check on the ram compatibly etc and damn gonna have to wait another day D: but i guess I'm lucky i didn't or else i would be devastated after putting it all together to find the ram wasn't compatible, and with the ram i was only looking so high(mhz) so when i decide to upgrade the gpu or cpu in the distant future thats gonna be still good for it (I'm sure 4133 would still be complete overkill, the 3600 would be probably the best choice but $26 extra in the long run would be worth it)

Personally I like to have a PSU higher rated than what I need (of course if the price is worth it) leaves room for other upgrades down the road. But that's just me, a 650W should be plenty and would be what I'd go with. Reason why I have an 850W is because I was going to do a 290X crossfire, but the prices skyrocketed before I could get a second one.
