Meanwhile an aftermarket RX 560 card would cost about only 50 USD...
That's because many Cryptominers bought and used these by the 1000s. AMD cards were better than Nvidia for mining and also cost less initially back then. Once the Bitcoin bubble got really big AMD prices went sky high in '17/'18.

Sometimes you'll find one used in good condition but it's still a gamble. Miners would flash the Vbios to a custom one that worked best for mining. It has to be flashed back to the original Vbios to work in a hackintosh.

The best bang for your buck AMD card right now is the 5500 XT 4GB card by Gigabyte. This does require a 450W + PSU upgrade and 8 pin supplemental power. Amazon has the best price. It's Navi RDNA based so requires Catalina to work with macOS. This is what you'd want if you're doing some serious FCP X editing and have the i7-4790 CPU in your Dell OptiMac. Also see the following post for another 5500XT deal on an MSI branded 5500 XT:

$20 rebate offer expires on 02/29/20.

Has three full size DP which is what you want to use with macOS. Only one HDMI and no DVI outputs.

Other great feature is that it's only 8.86" long so it fits well on the 7020/9020 MT motherboard.

@trs96 Thanks for putting together this great guide. I followed your HP 8300 guide and that worked out great too, thanks on both a SFF and a MT. I've now got the urge to build again lol.

I'm wondering if using an Optiplex 3200 SFF in place of a 7020 or 9020 makes any significant difference? I don't have one yet so I can still go for any model but I want to try and stay as low on cost as possible. I'd be tempted to go for i5 over i3 or i7.

I know the 3020 uses a different chipset and can accommodate less RAM but I don't think I would go above 8GB or 16GB anyway. It won't be my main machine. I'm not looking to do video editing or gaming but I would like to get 4K@60 Hz out of either the internal HD4600 GPU or possibly a separate card as it will be using a 4K monitor with a DP port. What do you think about this? Do you have any advice I'd really appreciate it.

Get a 9020 or 7020 SFF. These can be found at the lowest prices and let you add a low cost K600 card with DP output. Relatively small and quiet. Any of the Haswell i5s will work. Avoid the 3020s if possible. H81 chipset isn't anywhere near as good as Q87. Here's an Ebay seller that has a 3020 and 7020 with the same core i5-4590. Look at the prices. You'd save .07 by going with the 3020 over the 7020. Not really worth it to go the 3020 route.

I should have mentioned I'm in the UK really but I guess the price differences will be similar. Thanks for the advice I will look around for a 9020 or a 7020 and forget about the 3020.

I’ve decided to be brave and go for a 9020 i5 USFF. I know this will mean no K600 but I want to try out the fix for 4K@ 60 Hz from the HD4600.

That will be a challenge. It's very doable though. Follow nicksoph's guide and post there in his thread if you have any questions.

Thanks I will take a look. I fancy the challenge. I’ll give this a go and I can always sell on and get the SFF if it doesn’t work out. Providing I don’t brick it lol.

Is anyone else still getting these messages every few days? I've applied the fix but it's still happening. Not sure how to get rid of it
