New here and hope to get some help deciding on a gpu. I bought a new saphire nitro 7900xtx a couple of weeks ago. When it worked it was amazing. The issue was that during gaming I had no issues. But when I was on my desktop or simply starting an app like steam I would get constant freezing every 2 to 5 mins. These freezes would result in me rebooting my pc. I did the usual things like cleaning with DDU, different drivers and even a clean install on windows 11. I even tried asking on the steam forums with mixed answers. Anyway I decided to return the gpu as I thought it was bad. I have never in my 25 years of pc use ever had this issue. Now that the gpu is returned I thought about a 4080 super. One of the reason I picked the 7900xtx was its memory amount (24GB). With the 4080 its 16GB. So whats the performance difference between these gpus and how long would a 16GB gpu last.
