Help with CPU Selection for new Gaming Rig

I am planning to upgrade from my X58 System, but I am having a hard time deciding on the CPU... I don't intend to go for any extreme overclocks, but it will have something modest at some point. I'm also not sure i'm interested in dealing with deliding, which is why I keep leaning towards the 9700k over the 8700k, but the cheapo in me keeps saying the 8700k is close enough for a good savings.

Primary use is gaming at 1080p 144hz, occasional use is trans-coding rips for plex on my NAS. Either i7 is likely overkill for my use but I don't want to have to go through this again for a while.

I'll be buying the CPU and Motherboard at Microcenter, so I will be able to get the 8700k for around $300 and the 9700k for $370, plus tax. Likely the end of this week.

Parts:

i7 9700k or 8700k
Gigabyte Z390 Aorus Pro or Ultra
16gb G. Skill Trident 3200mhz CL16 - Purchased off of OCN already, i'll run this until prices come down or I find something worth buying.
GPU eVGA GTX 1080 - Already own
eVGA Supernova 850w G+ - purchased from evga w/ 12 year warranty
Corsair 500D (or my Alienware Predator 2 Case I am cutting up to add more fans and air intake.)
CPU Cooler - Right now I have an Enermax Liqtech II 240mm, likely going to get something else, need recommendations
SSD/HDD - Have this covered
Case fans - Arctic F120/140mm.


I really just can't decide on the CPU or cooler mostly. I will likely use the Enermax until I figure out what I want to do for a permanent cooling solution.

I want the system to be fairly quiet at idle, do the Arctic F120/140 fans perform quietly? I've seen them recommended around here.

My other option is a 2nd hand 6700k and motherboard - seems a let down from my 6c/12t xeon. I know it will be faster doing most things but it still feels like a step down. I might be able to still get it if it hasn't sold.


Thanks in advance! Happy Holidays!

Build looks good but I'd like to add in my experience and mention that two of my five Arctic F140 fans are already starting to fail and get quite loud after just a few months of operation. I got a good deal on them but I do recall my buddies saying to stick with Noctua and be done with it, to which I disagreed.

Again just in my experience - I have Antec 120mm tri-cool's that have run for over a decade non-stop without any issues; To have a nearly 50% trouble rate with the Arctic fans is an annoyance I could have done without.

Thanks for the heads up on the failure rate of them, seem like a decent price, maybe i'll use what I have for now and get some cash together for some nicer stuff.

Are you planning on a GPU upgrade anytime soon (while keeping the same monitor)? If not, any reason you are not considering Ryzen (100% would go Ryzen before getting a 6700k), I do not think really anything from the past few years is going to hold back a GTX 1080 @ 1080p144hz.

If you really want an i7, I would go for the 8700k and save the $ for your next upgrade [GPU and/or monitor]. Really, really nice CPU (sucks the price seemed to go up since I bought mine), not a fan of Intel getting rid of HT for the i7's, but oh well.

From experience, I had an 1800x and a 8700k (both with a 980ti and a 240hz monitor), at the end of the day I could not find a reason to keep the 8700k over the 1800x (the Ryzen gamed well enough [980ti is the bottleneck most of the time] and the i7 seemed like it would be an easier sell and worth more).

I'd go for the 9700K without a doubt. In applications that scale with nT the 8700K only wins by an extremely small margin and even that's not always. The vast majority of programs (and all games that I know of) only scale for 6-8 threads. The only situation that the 8700K makes sense is if your budget doesn't allow for the 9700K (or it cuts into other part's budget) or if you're doing some fringe use case that excels at parallelism and doesn't care about lower performing threads.

If games/programs start scaling with nT my recommendation goes out the window, but that's not the case just yet. I was stuck in the same boat a few days but decided to say screw it and went with the 9900K

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)
AMD X4 960T Zosma @ X6 4870mhz (+62.3%)
Intel i7 6700 Skylake @ X4 4709mhz (+38.5%)
Intel i5 6400 Skylake @ X4 4588mhz (+69.9%)

Honestly I'd wait one week for CES 2019 information on Ryzen 3rd gen because it is either going to be better than Intel or drop the price of the i7-9700K and lower by lessening demand.

Agreed. There's nothing wrong with high performance at a good price.

+1 for that. Unless you need a PC now I'd wait. That was my plan until my motherboard started acting questionable.

Intel i9 9900K Coffee Lake @ X8 5309mhz (+47.5%)
AMD FX-8320 Vishera @ X4 5022mhz (+43.5%)
Intel i5 4690K Haswell @ X4 5013mhz (+43.2%)

I just bought the GTX 1080 a few months ago, and it seems to perform well enough, even with my x5670 that I likely won't upgrade soon. I have not really considered Ryzen because I've been running intel systems since the day I bought an e8400. Prior to that I was a big fan of AMD. I have no allegience to either side.

I did briefly look into ryzen and I took away that it doesn't perform as well as the intel counterparts in gaming by a small margin, is finicky on memory, doesn't OC as well, and still runs pretty hot. Right now the Ryzen 2700x is $250 if I buy it with a MB. I am certainly not opposed to saving $120 on the CPU, that isn't chump change, but I also don't NEED to save that $120. I also have NO idea what parts to buy which means going back to the start and researching again.

The cost of the CPU isn't exactly an issue. but the 9700k is the absolute limit, ideally it would be the chip at the $300 price point, maybe next year? I've never bought a new i7 before, ever. Always the i5, and I always felt the need to upgrade sooner than I would have liked, but now it seems games are utilizing the cores. This time, for my first new build in quite a while, I want to go higher end. The ryzen chips certainly seem to provide bang for buck and are at least considering, this will further muddy the water... Do you have recommendations on a motherboard and RAM for me to start looking at?

Well, I don't NEED to upgrade at all, the x5670 does what I want, just slower than I would like. I ripped and transoceded 150+ dvds and 50+ Blue rays all to mp4 split between an i7 950 and x5670. Painful but it did it.

As for waiting, I am on vacation until the 6th, and this is the time where I will have time to focus on building, stress testing, cable management and then hopefully gaming for a while. If I wait, I get a couple of hours at night, at best once or twice a week. I have 2 young kids, they take up all the time I have. This system in some form will likely be my oldest sons first PC, hes 5 now, so 3-4 years? Probably sooner.

So Yeah I can wait for CES, but then I won't have the time i'd like to build the system. I'm not that concerned at the cost savings, I can't imagine it will make the $400 9700k drop to $300. Probably more like $30-40, right? There is also the 25% tariff on electronics that goes into effect next year. I am sure that will get passed on to the consumer at some point.

The main reason I am flipping between the 2 i7s is heat. the 8700k will need to be delidded at some point, and the 9700k doesn't exactly run cool either, plus no HT which has always been a part of the i7 chips.


Hopefully that answers questions about my questions.

I would go 9700K. 8c/8t seems to be the sweet spot for games right now, especially at 1080p 144hz. For multithreaded applications 8c/8t should perform about the same as 6c/12t. Maybe a little better if the 9700K can clock slightly higher than the 8700K. Plus no need to delid. With the 8700K there's also the cost of a delid kit, if you don't have one already. It can be done without a kit, but I would highly recommend it.
