Okay, to solve this question: RX-580 (8GB GDDR5) would work fine. Upgrade power supply to either aftermarket PSU (with 24 to 8 pin adapter) or use the 365W PSU (but it will cut it awfully close in terms of power consumption.) I even splurged a little and got my 4790K, and it does make a slight difference overall. Project is now finished. Now, what to do next... maybe go for a 9010 or maybe a newer model...who knows.

Hello again! I mentioned in my last post on what I will attempt to do next. So, I will attempt to get a 9020 MT, to sort of "complete" my collection. (I know there is a 9020 Micro, but I have no interest. If somehow I end up with one for free I'll figure something out if that time comes.)  My plan is: (once I verify everything works and BIOS is up to date) - Install a i7-4790K Processor in. I am already aware that I will need to replace the power supply with an aftermarket one, and I will need to get the 24 to 8 pin adapter.  - Max out RAM at 32GB. - Install 2 1TB SSDs and an extra Optical drive to compliment the one already there. -, Install an extra USB 3.0 hub into the PCIe (x4) slot. - Windows 10 (I have no plans to go to 11.)   Here's where I'm confused. I want to put a nice graphics card in for gaming. I know the PCIe x16 slot is a PCIe 3.0 standard, so I am looking at video cards that would use that. I want to give this PC the best chance it can. I would like to install a 6 or 8GB card. But, in using the Bottleneck calculator, it seems that there will be bottleneck no matter what card I use. But here's the thing... i don't plan on running games at their max setting. Probably medium to High, depending on the game. The two cards I am considering is a GTX-1660 Ti (6GB GDDR6, cheaper) and an RX-580 (8GB GDDR5)  Can anyone recommend any other decent cards for this?  Thanks!
