You're wondering if upgrading to the R7 5800X would work with your current setup. It's possible, but you should check compatibility and ensure your BIOS supports the new CPU. Since you've already updated the BIOS for the 5000 series, it's a good sign. Just confirm there are no conflicts before proceeding.
Certainly, it looks good. No upgrades required unless you need PCIe 4.0.
It depends on your GPU and NVMe interface. For models like the RX6600 or RX6500, you need PCIe 4. This GPU performs poorly on PCIe 3, while PCIe 3 support for NVMe Gen 4 will reduce speed.
Your present graphics card is an EVGA 2060 with 12GB of RAM, which seems sufficient.
You're referring to the RX6400 and RX6600 chipsets. The RX6400 uses just four PCIe lanes, whereas the RX6600 supports eight lanes. Eight lanes on lower-end cards are sufficient for PCIe 3.0.
Certainly! Your brain must have interpreted 6600 as a positive correction.
I thought it would work. Have you tried any more exciting options? For example, the 4000D Corsair is a good reference.
Air cooler versus AIO choice depends on your needs. The DeepCool AK620 offers solid performance similar to the Noctua NH-D15 but at a lower cost. The NH-D15 is clearly a strong option, though its price can rise significantly if you want black fans. The Scythe Mugen 5 works well but tends to be noisier. For AIO setups, a 240A model is recommended. Your current setup uses an older Corsair H100i Pro RGB XT for the 5900X, so upgrading to at least a 240A AIO would be wise.
I own a 5800x model too and am satisfied with its performance; it stands out among the better-looking tower coolers available. The installation mechanism was subpar, so I had to install double washers on the backplate to keep it stable. Previously, I used a 280 AIO with matching temperatures, but it needed replacement since the Fractal Torrent case didn’t fit unless I removed the front 180mm fans. I discovered that undervolting was the most effective solution. If correct, I set a negative core voltage offset of 1000 mV and used the curve optimizer at -18 in PBO. This lowered temperatures by around 10°C during load without affecting performance. Before this, it often reached 90°C under load.
