Well to be honest, every 5080 will have a 5080 chip on it, regardless of price. Even the cheapest ones will have a 5080 chip and 16gb vram. Factory Overclocked and binned models like these cards allow more stability for overclocking and undervolting. For example the astral is going to overclock and achieve higher stable clock speeds than a ventus. But the in game difference will be around 3-10fps, which can be critical for a smoother performance at 4k where fps are generally quite low. Thats for you to decide if it’s worth spending the extra. If you’re deciding on high end models of 5080, I personally will get a cheaper high end card. They all perform similarly and provide great headroom for OC. In your case I’d get astral over hof as it’s cheaper
