Is a CPU bottleneck really that bad? (infosec.pub)

Recently I asked about a new PC build. I got helpful responses about the topic but also a suggestion of just upgrading my GPU to a 3080 (from 3050). I looked deeper into it and it looks like I can do it easily even right now. Then I saw a 3080 FE for sale and I've always been a fan of how they look so now I want one.

However I also discovered that my CPU (i5-11400F) will be a severe bottleneck in that configuration. I don't really mind decreased GPU utilization and I'm pretty sure my CPU cooler will keep up just fine (tested in benchmarks and UE5) but will it give me any serious issues such as freezes or full on crashes? My resolution is 1080p btw (with the monitor itself actually being 768p but I increase resolution in games beyond that for better quality) but I might as well upgrade it to a 1440p one soon if necessary and use it for the new build when I undoubtedly waste my money on it.

You sound set on buying the 3080, which is totally fine I guess. It's not like it won't render 1080p games with great performance.

You're just going to be overpaying for an obsolete GPU that you won't actually be able to utilize fully, and will be bottlenecked on VRAM before games can actually push it fully. Meanwhile there are newer GPUs that will also render 1080p games with the same performance for less money. The 3080 has already aged out and has no future proof value so you'll just end up replacing it soon. So its just a really poor choice and poor value to buy one in 2025.

It had enough VRAM at the time and now is even considered one of the best NVidia GPUs ever made by some people

It's wild how wrong you are. The 3080 was widely received as a total flop and NVIDIA was heavily criticized for it because it was obvious they purposely put too little VRAM to encourage more sales of the 3090... It is the worst X080 series GPU NVIDIA has released and only had marginal performance uplift over the 2080.

EDIT: lol you can downvote me but it doesn't make me wrong

Like 5060 Ti for 1.5x the price and 20% less performance? Nah I don't think so. I think I know prices in my own country better ngl.

Ok, dunno why you're asking for help when you already know better lol. I tried to help you

Lemmy people seem to have the issue of completely forgetting the original topic. I noticed this earlier when asking about mouse compatibility on Linux and people started recommending mice for almost the price of a new PS5. I was asking about the potential bottleneck. I already did my research beforehand and confirmed that 3080 is indeed good value and suitable for my needs.

But... its literally not in any way...

Ok I'm pretty sure supporting such argument will get me banned for a few days but whatever. If you're so sure that there are better deals in my country, suggest me some options and I'll check them again.
