Is the 7800X3D a good match for the RTX 5070 Ti?

Yes. The 7800X3D is one of the best gaming CPUs of its generation, so it won't hold the 5070 Ti back at 1440p. The pair is balanced for high-refresh gaming.

Can it run demanding games like Black Myth Wukong?

Yes. The RTX 5070 Ti is built for 1440p at high settings, including ray-traced titles. Expect to tune settings in the heaviest games to hold a high frame rate.

What resolution is it aimed at?

1440p is the sweet spot for this configuration. It can also drive a 1080p high-refresh monitor with headroom to spare.

Is it easy to upgrade later?

It's a standard desktop build, so memory, storage and the graphics card can typically be swapped. Check the power supply rating before a major GPU upgrade.

Does it come with a warranty?

Skytech backs its PCs with a manufacturer warranty. Keep the receipt and check the terms for the coverage length and what it includes.

Is it worth it over building your own?

You pay a premium for assembly, testing and warranty support. If you value those and don't want to source parts, it's a reasonable pick; DIY builders can save by assembling themselves.
