All this talk about building a gaming pc for $1000 and keeping the iMac vs spending 3k on a new iMac misses a major point - why the hell is the OP just throwing his current iMac in the trash?!?

Wait. What’s that you say? He’s not? Oh, he’s selling it for 2k? Oh, that’s better.

Wait a minute... 2k + 1k and he can buy his new fancy 2020 iMac.
 
Ryzen CPUs don’t need 3rd party coolers.
You don’t have to spend $1000 to have a very good gaming PC, you can also spend $3000 if you prefer. However, this is all semantics at this point. Nobody is arguing that an iMac isn’t good for games, nobody is arguing that OP shouldn’t get a new iMac. It does seem like anybody having the gall to recommend something other than an Apple computer for gaming has hit a few nerves though.

I agree! +1 .. even my ryzen 3600x + 4 year old gpu (gtx1080) is squashing that unigen score (extreme).
I have FPS 144 and 3634.

A B450 motherboard is in no way a bad buy. It only got replaced by the B550 this summer, you still mostly can’t even find the B550 in stock yet. You can do practically everything you need to do with a B450, there’s very little that it doesn’t support that a X470 or X570 does support. For the majority of gamers a B450 or B550 is absolutely fine.

Ryzen CPUs don’t need 3rd party coolers.

And sure you can go for whatever SSD/HDD configuration you want but that’s kind of the point, you can choose what you like in a gaming PC.

We can discuss the merits of X part vs Y part all day but it isn’t adding to the discussion in this thread.

Absolutely! Your build is great value. The Ryzen 5 3600 is a fantastic chip for gaming and productivity. I also can attest that there is absolutely no need to stick a fancy noctua cooler or some other expensive cooler when the 3600 does completely fine with its stock cooler.

After AMD changed its mind, B450 will support the next gen Ryzen 4000 series CPUs if users ever want to upgrade the CPU, and it is a perfectly fine motherboard chipset. If you really need PCIe 4.0 support look for deals on B550 which pop up every so often (X470 and X570 offer very little extra for a gamer who wants to stick to a budget)

Although there's no doubting that the iMac now has pretty good GPU options, you're gonna get better gaming performance and way more mileage out of a R5 3600 system (with the ability to do a GPU swap far into the future) if gaming is a major focus for any user.

6 Core 12 Thread CPUs like the R5 3600 are extremely popular (for good reason) and I think that game developers will support them well into the future. Recent reviews of 4 Core 8 Thread Cpus like the Ryzen 3 3300X show that even those CPUs provide perfectly fine gaming performance.

It's only really the 4 Core 4 Thread CPUs like old Core i5s from the i5-7600 and earlier that don't cut it for higher end gaming these days. The GPU really is the most critical factor in a gaming PC provided your CPU is at R3-3300X performance levels or above.

If people really want to go Intel the i5-10600K/KF can easily give you the gaming performance of Intel's top tier i9-10900K at a fraction of the price, with a mild overclock (that pretty much anyone can do provided they are able to follow a 6 minute youtube video)

View attachment 943497Alright so the Unigine Heaven Benchmark has just come out for the 5700 XT and wow this thing is a monster!

For Comparison the Radeon Pro 580 in the 2017 5k iMac scored around 1100 so this thing is an absolute beast of a GPU.
Good score!
I only have my old 2012 27" iMac, but for comparison with my 16" MBP (base model 6core i7) connected to my 5700XT (to external 4k monitor) in my Asus eGPU box.

The iMac is quite a bit ahead!

The new iMac he listed will cost close to $4300 with aftermarket ram and assuming thats tax free. If you are paying tax then thats a $4500 computer in many locales. I'm not advocating what the OP does with his money but your numbers are completely off.

Unigine should not be a reference benchmark anymore. It's old, it's based on openGL, it doesn't use the CPUs very well.
A recent Metal Game from Feral should be used instead.
That or GFXbench (though it's not very high end)

The fact it doesn't use the CPU is a good thing in that it shows the capability of the GPU itself vs having the CPU masking a weak GPU.
 
No, if the engine only uses one CPU core, it's going to be limited by the CPU and will not show the GPU capabilities.
A good GPU benchmark should use all cores and be run at very high resolution.

Now I see what you're saying. Gotcha.

I was just going off the 3k number that was tossed around in this sub-topic of building a PC. I don’t care what the OP does with his/her money. If it were me, I wouldn’t upgrade. Just saying that there’s more than just the outlay of cash to consider. Macs have great resale value and that fact often gets discounted when talking about the costs of being a Mac owner. A 3 year old PC would be good for a tax-write off. A 3 year old Mac is still worth a good amount.
 
Lol, I was waiting for someone who didn’t read everything to reply with this. Nobody is saying that is a replacement for an iMac. OP wanted to upgrade their perfectly good iMac so they could play games better. It has been mentioned a few times that they should just keep their iMac and build a separate gaming PC if that’s what they want it for because they’d spend a fraction of the price and they’d have the best of both worlds.

Also, lol at having a 5K screen on a gaming PC anyway. That would be entirely pointless because nothing can play games in 5K. Everybody knows that the best type of monitor for gaming is something 1080P/144HZ or 1440P/144HZ 😉

FYI, you can add a faster NVME SSD than the iMac has and still be under budget.

But what if the user has no other monitor other than the iMac? You need to add at least around $100 for a separate monitor that a Windows PC can use.
 
Decided to throw my test into the mix. Ran it at 1920x1080 instead of the 1600x900 Extreme preset. Still pretty impressed for a Mac! Looks to be a little bit better than a GTX 1060 :)

The Radeon 5700XT is supposed to be much better than a geforce 1060, but this benchmark is not well optimised and openGL is slow on macOS.
1080p is not enough to test a GPU with this old tool. Try 1440p or even 4k if it's supported.
 
Yeah, you can't really compare Mac scores with Windows scores.
The score I posted earlier on the "Extreme" preset with my 5700XT in an eGPU box (with 16" MBP) was like 70 FPS and 1780 Score. When I tested the exact same card in my Windows PC (Ryzen 9 3900X/X570 mobo/32GB) I scored double that at 140FPS and like 3400ish score on the same Extreme settings.
Of course, there is a 10-20% performance hit for using the GPU in the eGPU box, but still it is quite a difference. OpenGL hasn't been updated on Mac in a long time.

I’ve heard via Matt Moniz who did some benchmarks and testing on his 10 core 5700 XT loaner from Apple that he thinks the 5700 XT is roughly the same performance as a RTX 2070 Super or RTX 2080 MaxQ so this card really is indeed a beefy card. The 3D Mark Fire Strike score is the same as the two GPUs I just listed so it makes sense it would bench around those GPUs. To put things in comparison, the RTX 2080 Super scores about 4000 points higher in the fire strike test coming in at around 22,000 where as the 2070 Super, 2080 MaxQ, and 5700 XT is around 18,000. My Radeon Pro 580 from my 2017 5k iMac scores around 6600 fire strike so its a huge improvement overall.
 
I can’t see how this new iMac would game at 5K while a 2080Ti still have pain to play at 4K on Windows.

You would play comfortably at 1440p which is 1/4 the size of 5K so it'll fit cleanly with 4 pixels for every pixel. Same way you run 1080p applications perfectly on 4K displays. My Vega 64 runs most games very well at 1440p so I'd imagine a 5700 XT would be more than capable in anything but the most demanding games.

Correctly stated. Max Yuryev should be posting his video Friday and over the weekend with some nice tests and benchmarks and comparisons so this weekend should clear up any remaining questions people might have.

Ok I see. I never play games so I don’t know this at all.

But lets keep this honest....there was more than one number being tossed around but you chose the 3k number to fit your point that it would be exactly the same amount of money in total for the OP to sell his current iMac for $2,000 and spend an additional $1,000. I understand you can resell iMacs for a good amount of money and that is a valid point but using highly incorrect numbers to fit your point perfectly doesn't help the discussion when it's completely wrong.

There's about a $2500 difference(give or take) after the sale not $1000....we are talking completely different numbers.

Max Yuryev is scheduled to get his new 10 core 5700 XT model tomorrow and hopefully his reviews are on Friday/this weekend so we can get a really good look at thermals and performance. I will keep everyone updated!

This is the exact review I'm hoping to see. I've been refreshing his channel once a day for over a week lol
