I have a home theater PC that I use for Windows Media Center for my cable service (using Xbox 360's as extenders for my other TV's), Plex Home Theater, Blu-ray playback and once in a while, some mild web surfing.

I recently upgraded from a 1080p display to a 4k TV. It's a Samsung 70" 630 series, so it has 4:4:4 Chroma scaling, low end HDR, 2.0a HDMI.

Rig:
ASRock H97m-itx motherboard
Intel Core i3-4330 (Haswell) CPU
4GB of ram
Thermaltake 450W PSU
240GB SSD
1TB Hard Drive
LG Blu-Ray player
Cooler Master Elite 120 case
Windows 7 (I am running WMC, so I can't upgrade to Win10).

When set to 4k @ 30Hz, video (especially faster motion) is choppy. Verified in both Plex and watching content in WMC. TV does not do that on the same port, even on 4k content, with both my FireTV and the built-in TV apps. From my minimal research, the integrated HD 4600 graphics can't keep up.

I want a BUDGET video card. No gaming. I want to do 4k @ 60Hz with zero issues. I typically go Nvidia so I plan to stay that way unless there is a super-budget AMD card that will meet my needs.

I've seen the GTX 1050 for $110 and a 1050 ti for $140. Anything out there cheaper that will work? I would go used but people seems to be asking near enough to new prices I won't bother. 950's seem to be the same price. Since I just blew some cash on this TV and just bricked my HK receiver doing a firmware update (that I am sure HK won't do anything for me on as it is out of warranty, even though I followed their process), I am on a budget for this upgrade.
