Which GPU? – Underpowered Rig, 4k Display


The year before last, I built a budget PC with a GTX 970. It developed a fault and they gave me a refund. I haven't replaced the GPU since. Now I'd like to play DotA 2 and a few of the newer titles, perhaps Civ6, Batman, Tomb Raider.

To complicate things, my monitor is a cheap 60Hz, 4k display and looks terrible below native resolution. Therefore, I need a card that can handle 4k to some extent, perhaps at medium to high settings.

I don't mind spending money on a 1070, but I think it'd be too powerful for my rig. My CPU is an i5 4430. There's so much conflicting information on whether it'll bottleneck or not. I'm fairly sure I was CPU bound playing GW2 with the 970 so upgrading from that doesn't bode well. I also only have a 500W PSU.

My full part list is here:

I'd rather not upgrade other components if I can help it. I'll probably build a new PC in a year or two and give this one to friends/family. I'm not really sure what to do. Buy a PS4 instead?

Your expert wisdom would be most appreciated!

    As Resolution increases, it puts more load on GPU not cpu. Increasing resolution doesn't change things like draw calls, which are cpu intense.
    A GTX 1080 is about as good as it gets right now on a single gpu.,4572-8.html
  2. I want to ask you some questions myself- what is your screen model? And do games look bad on all lower resolutions, or 1080p is fine?
