Recommendation for 4K capable desktop computer build

hmmwv 2,142 226 February 7, 2017 at 12:39 PM
Ever since I got the Samsung 40" 4K TV as my primary monitor I've been trying to get a 4K capable computer. I use the computer mostly for office, Internet, video editing, and some very light gaming (pre-2012 titles). I want to be able to use it for at least the next 3 years.

Initially I got the Lenovo E570 with GTX950M but it turns out doesn't have HDMI 2.0 so I'm stuck with 4k @ 30Hz which has annoying lags. Then I tried to do an external GPU with my current laptop (Thinkpad T430 without dedicated GPU), but it turns out this model can't do external GPU due so some weird memory allocation problems.

So now I'm back to square one, laptops rarely has HDMI 2.0 and the ones do cost way too much. With my budget of $450-500 I think my only option is to get a desktop again.
I already have a micro ATX tower, 450W PSU, SSD and DVDRW from a previous parted out desktop. So I just need CPU, Motherboard, RAM, and video card.

Here is a list of hardware I'm thinking about getting for $500:

Intel Core i5-7500 (~$195 AC)
MSI B250M PRO-VDH Motherboard (~$80)
Mushkin Enhanced Blackline 16GB DDR4-2400 (~$90)
MSI Nvidia Geforce GTX 1050 Ti 4GB (~$135 AR)

This configuration represents the high end of what I planning on getting. I'd appreciate any recommendations of means to save some money as long as performance is comparable. I'm thinking maybe a cheaper Skylake CPU, or video card with 2GB GDDR5?

In order to game at 60hz on a 4k monitor at high settings, you need a minimum of a GTX 1080. If you are willing to drop the quality settings a bit to maintain the 60fps, you can get by with a GTX 1070.

EDIT: After re-reading your post, you shouldn't have too much trouble running older games at 4k with that card, but you won't be able to play any modern AAA titles.

Yeah I don't plan to game at 4K, 1080p at most, and gaming is way down my list of priorities, I just want to have a smooth 4K experience for normal office / Internet / movie usage.

Your onboard GPU is supposed to be able to play 4k (video, not gaming) just fine on Kaby Lake. Thats one of the benefits of it that changed. http://www.pcworld.com/article/31...iends.html

So I would start there and add a GPU if you need later.

For building a PC I can't recommend PC Partspicker enough. Not sure of the PSU you have but quality is pretty important, last thing you want is a low quality PSU to cause you problems.

I agree I'd be okay with IGP if it supports 4K @60Hz, but the problem is that I can't seem to find a motherboard that has native HDMI 2.0 port to take advantage of Kaby Lake's 4k capabilities.

I'm in total agreement. If you want smooth movie watching at 4K, you should be able to pull it off with a Nividia GTX 1070 and higher or AMD RX-470 and higher. I don't think the GTX 1050 Ti will have enough to get it done smoothly unless you tune down a few settings and not go as full quality as you'd like.

I assume you mean RX470 or higher, right? Because isn't the 1050 Ti faster than a RX460?

Yes, indeed. Didn't do a well enough comparison check on those two specific models. I corrected.

Movie watching should be fine with an integrated GPU (assuming the resolution and refresh rate are supported). Very little is processed by the video card, and even that is usually by dedicated video only parts, unless you have some special software like SVP (SmoothVideo Player) that does the frame rate interpolation. Games are another story.

I'd try to look up a few of the games you want to play to find out how they run on different GPUs at 4K. Some might not even support 4K as an option.

And Kaby Lake is pretty new (right?), so not surprising if there isn't hardware available to exercise all the new features it'll eventually offer. I haven't tried to compare it to the previous generations, but most of the last few Intel families haven't had astronomical differences in performance. So you might be right that you could save some money, and not lose much by getting a Sky Lake instead.
