[SOLVED] Looking to upgrade GPU of older computer

[Axil00]

Ok, so I have two PC's that are 2013 and 2015 builds respectively. Id like to get at least another year or so of decent 1080p gaming performance out of them, and am trying to decide what GPU makes the most sense in this scenario.
Here is my current hardware:

Older Rig

Case: Fractal Design R4 Black Pearl

PSU: SeaSonic G Series 550-Watt ATX12V/EPS12V

Motherboard: Asus P8Z77-V LK Intel Z77 DDR3 LGA 1155

CPU: Intel Core i5-3570K Quad-Core Processor 3.4 GHz 4 Core LGA 1155

CPU Cooler: Cooler Master Hyper 212 EVO - CPU Cooler with 120mm PWM Fan

GPU: GIGABYTE GeForce GTX 660 Ti WINDFORCE 2X OC Edition 2048MB GDDR5

Memory: Kingston Hyper X Plug n Play 8 GB Kit (2x4GB Modules) 1600MHz

SSD: Mushkin Chronos Deluxe 240 GB SATA 6.0 Gb-s 2.5-Inch Solid State

HDD: Seagate ST2000DM001 Barracuda 7200RPM 2 TB SATA 6 GB/s NCQ 64 MB

OS: 64bit Win10

Newer Rig

Case: Corsair Carbide Series Black 500R Mid Tower

PSU: Rosewill CAPSTONE Series 550W 80 Plus Gold Certified ATX12V/EPS12V

Motherboard: ASUS MAXIMUS VII HERO Z97 ATX DDR3 2600 LGA 1150

CPU: Intel Core i7-4790K Processor (8M Cache, up to 4.40 GHz)

CPU Cooler: PHANTEKS PH-TC14PE_RD

GPU: MSI Computer NVIDIA GeForce GTX 970 GAMING 100 Million Edition OC 4GB

Memory: Kingston HyperX FURY 8GB Kit (2x4GB) 1600MHz DDR3 CL10 DIMM - Blue

SSD: Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD (MZ-75E250B/AM)

HDD: Seagate 3TB Desktop HDD SATA 6Gb/s 64MB Cache 3.5-Inch Internal

OS: 64bit Win10

Now my plan is to purchase a new GPU and a set of 16gb of ddr3 for the older PC. Then i would move the 8gb i already have on that one to the newer one, so both end up with 16gb. I know the newer PC would get more use out of a better card, but that isn't the one i'm able to use for gaming most of the time.

So the graphics cards i'm looking at are the RX 580-590, and the GTX 1660-1660 TI. The goal would be to be able to play games at 1080p on high graphic settings with a decent frame rate. In a year or so i'm looking to replace the older PC completely and will move whichever card i get now into the second rig one.

Hopefully all of this makes sense, i know it's a bit of an odd request.

So I guess these are my questions/concerns:
1.) Will the 3570K give me a good gaming experience at 1080p with any of those cards, or is it just too old now. I've tried to research this but have come across a wide array of opinions on this.

2.) Will any of these cards allow me to use a 144hz monitor at 1080P high settings with either of the PC's i currently have. If so i might consider grabbing a 1660TI, as at some point i'd like to try high refresh gaming.

3.) is there any reason to believe prices will get substantially better in the next couple months? my 660TI has had some issues so i'd really like to replace it soon, but if i can save some money by waiting I would definitely consider it. Not sure on the timeline/pricing of the budget Navi cards


Thanks to anyone who took the time to read this, i appreciate any help you're able to provide.

About 4 years ago I bought a second-hand computer with an i5-2500k and 350w PSU. I put a GeForce GTX 970 in there and I ran high-end games like GTA5 and such on high settings. So I bet your 3570k will do just fine.

All the cards mentioned above should be able to get you 144hz on 1080p easy.

I don't really think prices will go down that far, but since nVidia just launched their 20 and 16 series, maybe some time will save you a buck.

Also, you might want to try and install the memory of the old PC in the new one, just to be sure it works (it should though).

Kind regards.
