My current system has an Intel i7-4770K, 32 GB of RAM, and one MSI GTX 1080. I mainly play at 1440p and 75 Hz, though I occasionally play single-player games on a nearby 75-inch 4K TV. I originally used two GTX 1080s for 4K gaming, but that monitor died last year.
I built this computer when the GTX 1080 launched. I still play games, mostly on weekends, but I'm interested in upcoming releases and would like a smoother experience without spending far more than necessary. I'm in Canada, and I would need to travel about two hours to reach a city with suitable parts or systems.
One option is to buy a GeForce RTX 5080 for roughly $2,300 CAD and install it in my current system, but I'm concerned the old CPU and platform would severely limit it. The other option is a prebuilt system costing about $4,200 CAD with an Intel Ultra 275K, 32 GB of RAM, and an overclocked RTX 5070 Ti. I have the money for either option, but I'm unsure whether the complete system would provide enough of an improvement over simply adding a 5080 to my existing computer.
I've always used NVIDIA and would prefer to stay with it. Building a system myself is also risky because I tend to keep upgrading until I choose the most expensive parts available. What would be the most sensible route for someone who games casually but wants to enjoy newer titles for several years?

If you’re focused on 4K gaming on the TV, target a complete new system rather than upgrading only the graphics card. At 1440p and 75 Hz, you don’t need an extreme flagship setup, and at 4K the GPU matters more—but the old processor can still cause inconsistent frame times and poor minimum FPS. A balanced new computer is the safer long-term purchase.
A modern CPU upgrade makes a huge difference compared with that fourth-generation Intel chip. Newer systems also give you faster storage, current PCIe support, better power delivery, and access to DDR5. You could build a balanced system around a Ryzen 7600X, 7800X3D, or newer X3D chip and spend the remaining budget on the strongest GPU that fits your actual resolution and refresh rate.
The i7-4770K is old enough that pairing it with a modern high-end GPU would be a major mismatch. You would run into CPU limits, and the older motherboard, PCIe support, power supply requirements, and memory platform could all become problems. A 5080 in that system would not deliver what you’re paying for.
I’d replace the whole system, but I wouldn’t automatically choose that $4,200 CAD prebuilt. Look for a balanced modern gaming build with an AMD X3D processor, 32 GB of DDR5, and a GPU in the 5070 Ti class. That should be much better balanced and could cost less than the system you found.
For a weekend gamer, spending $2,300 CAD on a 5080 may be unnecessary unless you specifically want maximum settings at 4K. A used or lower-priced modern GPU could be plenty for 1440p, while you save toward a new platform. If you buy anything above the midrange, though, the 4770K becomes a serious bottleneck.
The prebuilt is mainly appealing because it’s the fastest suitable system I can find within driving distance. I’m trying to avoid building one myself because I’ll probably keep adding expensive parts until it gets out of control.
