I'm planning to build a new computer as, after 8 years of faithful service, this one is starting to fail. I'd like to be able to run modern games on high settings at 1440p and 120+ FPS, and for the system to last for at least 4 years.

I have some money so I'm not capping the budget. But the prices of some parts are eye-watering - especially since I haven't looked at this stuff in 8 years! - and so I'm looking to keep costs on a leash and get value for money where possible.

The other thing I'm conscious about is power draw. Not just because of electricity bills, but also the additional costs and complications in terms of exotic cooling systems, and the general inconvenience of a system that belches heat and noise.

Hopefully this gives you an idea of how, after looking at lots of reviews, benchmarks and comment threads courtesy of this fine site and community, I hit upon this strange proposition.

My hope would be that the savings on the 5800K3D (and attendant savings on mobo, DDR4 etc) would offset the price of the 4070Ti while not compromising on game performance, while also keeping power draw low. I figure I could live with the relative under-performance for other tasks.

I am however all too aware that I might end up with a lamed system that bottlenecks an expensive GPU with an inadequate CPU. In other words, an exercise in futility and hubris!

I wondered if you fine folks could weigh in on which outcome you consider more probable. And if you had any suggestions for alternative pairings, I'd be grateful for those too. I was considering waiting on the 7000K3D series reviews to come in, but looking at the specs it seems much of the (perceived) advantage in terms of savings and power efficiency would not be preserved.

Please be gentle, I'm new to much of this!

Hello again! I'm sure you've all been reading the reviews of the 7950X3D - exciting stuff, eh? And the Tech Powerup simulated7800X3D 'review' only adds further felines to the pigeon melee. I have to admit that, even only using speculative specs, I find the talk of excellent gaming performance, adequate productivity and remarkable power efficiency of the 7800X3D incredibly tantalising - it seems to be everything the 5800X3D is, only moreso (including price, natch).

This predictably has me in two minds. I'm very tempted to hold off now, although availability is a concern - do you think it will be difficult to get a hold of one of these at launch? I'd hate to wait only to lose out to scalpers or just a general gamer stampede.

So I decided to try and pit my best speculative builds against one another, amateur though I am. I was hoping people could look them over and tell me what they think.

Since PCPP doesn't have the new processors in the DB yet, the 7800X3D build uses a substitute processor that is slightly less expensive than the intended CPU's RRP. However, this is almost exactly balanced by the absence of listed price for the cooler on the 5800X3D build (about £30 each). Also, the monitor is overpriced by about £100 since I saw one on Amazon for around £480 as of this morning.

I'm not sure what this warning from PCPartPicker means, could anyone tell me if I should be worried? "Note: The video card PCIe 16-pin power connector adapter is being supplied by three 6+2-pin power connectors. Please ensure that the three 6+2-pin power connectors are not daisy-chained and do not share the same power cable."

As you can probably tell, I only half know what I'm doing at the best of times. I found the motherboard a particular nightmare to pick for, as there's a matrix of features you need to keep in your head, each with its own sub-matrix of parameters. It seems an iron rule that only one board will have everything you want, and it will cost twice as much as you're willing to pay. But you can probably knock off as much as £100 on the 5800X3D build since the Aero is a somewhat extravagant choice that could probably be downsized with some more effort.

Even so, at a maximum of £300 difference, it seems to me that at only 12% more the 7800X3D build wins out pretty clearly?

I'd love to know what you guys think. Yes, even about all the schoolboy errors I've made :D

That warning means you use a single PCI-E power cable, per connection. Some cables have two 6+2 connectors. Don't use both connectors. If you get the Corsair 12v high power cable, you don't need to use Nvidia's ugly adapter.
https://www.corsair.com/us/en/Categ...0-12VHPWR-Type-4-PSU-Power-Cable/p/CP-8920284

If going with DDR4 3600, it should be CL16, not CL18. 3600 CL18 is just as fast as 3200 CL16. It doesn't cost much more, to get it either.

That monitor is pretty nice, but the cost not so much. Other than lightweight e-sports titles, I doubt you would ever fully utilize that 240hz. Trimming a bit of fat off the monitor price, would allow you to get a faster GPU, like a 7900xtx, which also eliminates that adapter you have to use with RTX 40 series cards.

On the AM5 side, you ideally want either DDR5 5600 cl28 or 6000 cl30.

Thanks guys! I really appreciate the advice and suggestions, the info about RAM was especially helpful. I guess I'll start buying parts common to both builds where the prices look good. The final decision can come later (although I think I might have already set my heart on the 7800X3D).

Hello hello! I'm back again with (hopefully) one last question.

I talked myself into the 7800X3D - inevitably! - and now most of the parts are ordered. I just have to decide on a cooler. I noticed the Tom's review suggested (via AMD) at least a 280mm water cooler, but I was wondering if there were any air cooler alternatives. I noticed that Noctua rate some of their best coolers as being 7800X3D-compatible, so I was encouraged to look further.

From reading around on water coolers, I'm a bit wary about issues regarding reliability, as they're more complex and I have no experience installing one. Generally they don't seem to be rated to last as long as air coolers, which is also a bit discouraging.

That said, my primary concern is about performance in two areas: cooling (obviously) and noise. I was fortunate enough to find this TechPowerup review which offers a comparison of the two candidates I have narrowed it down to, the Be quiet! Dark Rock Pro 4 air cooler and the Arctic Liquid Freezer II 280 water cooler. Looking at the cooling and noise comparisons, it seems they perform near-identically at idle, while at higher loads the Be quiet has the edge on noise (by 5-6 dB) and the Arctic has the edge on temperature (by 3-7 degrees C).

My primary use case will be gaming (with potential for long sessions on the weekend), but I'll also be using it for extended periods of work. I don't intend to do much overclocking. I checked around for ram and mobo compatibility on the Be quiet (it's big) and think I'm in the clear. If we don't think about price for the time being, which of these coolers would you go for?

Either would be fine. AIOs typically last anywhere between 2-6 years with the pump dying or permeation of most the liquid inside the loop being the main points of failure.

I don't think the 7800x3d is going to be particularly hot. Any good high end air cooler should keep it inline, especially when gaming as it's not going to be at 100% CPU usage or likely even close.

From a case standpoint you may want to consider something with a mesh front. Maybe a lian li Lancool III if you're looking for the best temps. Gamers Nexus has some pretty great case testing videos.
