    I tried to find out which AMD GPUs support 4K video but according to wiki it looks like only the recent, high-end models do: https://en.wikipedia.org/wiki/Unified_Video_Decoder

    my recommended searches to score a decent nVidia card in the $40-or-less range would be:
    GTX 650
    GTX 660
    GTX 750
    GTX 950
    GeForce 640 GDDR5
    GeForce 740 GDDR5
    GeForce 730 GDDR5
    If memory serves, the 560 Ti uses GDDR5. I mentioned 2Gb cards mainly because someone in another forum they solved their 4k problem by upgrading the video ram from 1Gb to 2Gb. I doubt I could do that with this card.

    It sounds like a comparable GPU would cost me $60+, so I need to decide if I should buy that, or get a newer power supply; obviously not the $55 special on sale.
    PSUs usually have a 3-5 year warranty on the low end and 7-10 years on the high end. Even if it is not under warranty, it's still cheaper to invest in a new power supply than a new video card.

    It's especially important to get that power supply out of the system if its so marginal that it rolls over and dies with just a video card added for a load. If you plan on upgrading the CPU as well, it'd also probably not work with the malfunctioning PSU.

    This echoes what I've been thinking. $20 PCIe cards might be useful in replacing motherboard chipsets, but not much else.

    Been doing a little snooping around, and it appears my friend was more generous than I realized. A card with equivalent performance to the 560 Ti runs $150-$200 new.
