I currently have 32GB of DDR4 memory and a i7-7700K 4.2Gz processor. That processor is the best my motherboard can handle, to get the chipset above that I'd need to change motherboard. So my question is, what GPU do you think is the best that I could get without my CPU becoming a bottleneck?

I don't think the CPU would be a bottleneck in your case with any GPU. Get the beefiest one you can afford. The price of GTX 1080 Ti's should come down in the near future since the new generation is due out soon. Or if you have a spare kidney, you can go for the RTX 2080 Ti :).

The 7700K will handle the RTX 2080ti and even cards that come after that easily. Unless you are bothered by singular FPS differences or some groundbreaking technology appears in the CPU department, you are absolutely fine with what you have right now.
Actually getting CPU bottlenecked in games these days is extremely difficult. Don't believe people that say otherwise. The 7700K will take a loooong time to become a bottleneck of any kind.

What they said -- That's a beefy processor, and at the pace processor technology is moving, I don't see it becoming obsolete any time soon.

Also, with that kind of hardware and a matching GPU ( GTX 1080 and upward ) you probably don't want to limit yourself to 1080p, and at higher resolutions and lower framerates your CPU is even less likely to be a bottleneck for the GPU performance.

With that hardware you should be set for a good while, so as everyone else has said, just get 1080 now, if you can afford it or wait a while for the 20XX cards to hit the market and go to either those or get a discounted 1080.

Thanks bros. I've had my eye on a 1080ti for some time but have been waiting for the price to come down.

Black Friday is pretty close. Just wait another two months and you should be able to easily find a reasonably priced 1080 ti.

And hope that Black Friday in Australia isn't Black Fraierdai (suckerday) from Romania :).

I'll admit that most of the deals here in Romania are fake(advertised as -50%, when in fact the base price was bumped up prior to applying discount, thus making the actual discount only 10%-15%), but there are also really good sales, if you are lucky or skilled enough to search for them. I'm yet to get tricked by this ?marketing pratice?.

I disagree. The 10 series cards are not coming down. There is no reason why they will, since they are still in extremely high demand, and that isn't going to change. Nvidia has a total monopoly over the market and competes with no one except themselves, and they are using that as the basis from which to exploit their customers.

They deliberately priced the 20 series at extortionary scam prices so that people who are not rich will be forced to buy the years-old tech of the 10 series at around its full MSRP, even though it shouldn't be worth that much any more since it's old.

And this way, people are buying 10 series cards in droves for way cheaper than the 20 series, and are happy because they think they are getting a "deal," even though they are really not.

So Nvidia gets to offload all their old obsolete 10 series cards at full (or almost full) price, and also take in obscene amounts of money from the rich people who buy 20 series at outrageous insane prices. It's a win/win for them. But for consumers, it's a horrible situation.

Ancient Dragon is right - the price will not be coming down.

Consider getting an RX 580 instead. Around $250. Can handle anything you throw at it in 1080p - except PhysX.

What I saw is that most crap which hasn't sold well is discounted, but really good quality stuff are rarely discounted extremely.

I'm agree with you. AMD needs for being to solve the problem of the high power consumption of their graphics cads or this isn't to change (and even then, also the AMD Vega cards are overpriced).

I read the information which you are actually mentioned in your post I am also asking the same thing to the Hp Support Assistant to know the thing properly,m if you know the proper information you can also visit the site, I think this site will help you a most.

Should not have an issue with 1080ti or higher on cards. all I know is if you are planning on 4k only gaming then cpu means shit and its all graphics card power with ram to a degree.

if you are doing 1440p then you are in the middle and it requires both good cpu and graphics card. 1080p is more cpu bound.

at the end of the day it's all up to you on what you want. 7700k is still good for gaming at 1080 and 1440p but if you really look at benchmarks 8700k and higher can yield 20 to 30% more fps in games when using higher clocks with those resolutions when tied to the latest graphics cards.
