I'm putting together a mostly secondhand gaming PC and found a bundle containing a Ryzen 7 5800X, 32GB of DDR4 memory, and a B550M-Pro motherboard for about $600 CAD. The rest of the proposed build is an RTX 5080 for $1,500, an 850W power supply for $100, a case and fans for $80, a 360mm liquid cooler for $80, and 1TB of storage for $160, bringing the total to roughly $2,500 CAD. I'll mainly be gaming at 1440p with a 165Hz monitor. Would the AM4 platform and 5800X significantly limit the RTX 5080, and is this overall build a reasonable deal?

It probably won’t be a severe bottleneck in every game. At 1440p, the graphics card usually does most of the work, and a 5800X is still a capable processor. The impact will depend heavily on your settings, target frame rate, and games. For a steady 165 FPS in CPU-heavy titles, though, a newer CPU would be preferable.
It may be worth comparing the build against a Radeon 9070 XT system. The 5080 is faster, but in ordinary rasterized gaming the difference may not justify the extra cost, and the 9070 XT can be easier to balance with a less powerful CPU. That said, if the 5080 price is genuinely about $400 CAD below normal, the deal changes considerably.
Ray tracing and especially path tracing can change the comparison, since the 5080 may pull much further ahead in those workloads. The decision really depends on whether those features matter to you.
The 5800X will limit a 5080 in some situations, especially competitive games, simulation titles, and anything where you’re chasing very high frame rates. At 1440p, many visually demanding games will still be mostly GPU-limited, so it won’t make the card unusable, but you probably won’t get the full performance you paid for. Since the 5080 is already a premium-priced card, pairing it with an older mid-range CPU makes the overall value less convincing. Check benchmarks for the specific games you play and consider a newer platform if the budget allows.
The discounted 5080 is the main reason I’d still consider it. It’s more expensive than a 9070 XT, but a large enough discount could make the performance and feature set worthwhile.
