Radeon RX Vega56 is a good choice for gaming at up to 2560x1440 resolution
Wow. GPUs have dropped in price recently. That's a good deal for that price range. But as others have said: "Navi" is launching in July-ish. GPU prices are expected to decline as new cards come out. But you probably wouldn't feel bad to snag a Vega56 at those prices.
I'd recommend that you buy the $300 one. The $270 one at the top of the list has a reference cooler: which is louder than what most people expect. The PowerColor RED DRAGON would be quieter and probably be cooled better with the triple-fan setup. Quieter and cooler is worth the $30.
This one from Reddit is pretty informative and it has led me on to believe I should invest in an Nvidia GPU rather than AMD. GTX 1060 from this list seems pretty good for the price but I'm wondering how long will it last me considering the upcoming titles. I'm guessing it's not good enough for CP2077 but I'll be able to upgrade in 1,5 year when I save up more cash.
GPU prices change often: they go both up and
down in price. Maybe at the time that post was written, NVidia was better. But today, that Vega 56 that JustAnEngineer is pointing at is looking pretty good. The Nvidia 2060 is $370 at the moment, which means the current "equal price" matchup is NVidia 1660 vs AMD Vega56. It seems like AMD is better at today's prices.
AMD does run hotter than NVidia (NVidia has been better at optimization). But the Vega56 is much more powerful than a 1660.
As for PSU, I got this one from Amazon a few years ago, I believe it should be fine since it's 500W.
Uh oh. Well... that's where the increased power usage of a Vega56 will be a problem. Vega56 needs more power than that. Hmmm... does anyone know how much power a NVidia 2060 usually uses? It might be cheaper to "upgrade" to the 2060 if its going to remain under 500W. Otherwise, if you get a Vega56, you'd probably want to get a new PSU.
Vega56 definitely wants a 600W or even 700W power supply. It turns out that Vega56 and Vega64 have extremely high transients that were causing issues for some people's builds. Basically, Vega56 will draw a bunch of power (sometimes) for 20ms or so, which caused some 500W power supplies to trigger the over-amperage safety shutoff. Your 500W PSU may be fine, but its going to be a risk.
Hmm... you could always just buy the Vega56, play a few games, and see if everything is fine. If it doesn't work, you can always switch to your old GPU while you order a new power supply.

The measured transient was ~20ms of 51A at 12V, or ~600W transients (the oscilloscope shot was of a Crossfired 2x Vega56 setup, in case you're wondering why its 100A in the oscilloscope screenshot
. This suggest a 600W PSU at the minimum (but remember that the CPU and the rest of the system will also be drawing power), so 700W+ would be safest. A 500W PSU may still work because its just a "temporary power spike", 20ms at a time, but you'd definitely be running your 500W PSU outside of its specifications (albeit only for 20ms but still...)
