Look, honestly, since you have an RTX 4080, you really need a 240Hz panel to get your moneys worth. I've tried many mid-range screens over the years and cheaping out on the panel is the fastest way to ruin a high-end build. That ghosting you're seeing usually happens because the pixel response time can't keep up with the frame rate. Since you're heading to Micro Center, definitely look for the LG UltraGear 27GR83Q-B 27-inch QHD 240Hz IPS. It usually sits right around $350 to $450 depending on sales, which fits your budget perfectly. In my experience, LGs Nano IPS tech is the gold standard for avoiding that smeary mess in fast games like CoD or Apex. The 4080 is gonna absolutely crush 1440p, so sticking with 144Hz actually feels like a waste. Going 240Hz gives you that buttery smoothness that makes the 1080p jump feel like a massive upgrade. If they don't have the LG in stock, the Gigabyte M27Q X 27-inch 1440p 240Hz IPS is another solid alternative I've used for a few builds recently. Just make sure you use a DisplayPort cable to actually get those high refresh rates working properly. You're gonna love the clarity once you ditch that old screen, its night and day.
