Which is better for 4K gaming?

They are effectively tied. Both pair a Ryzen 7 7700X with an RTX 5070-class GPU and 32GB of RAM, so frame rates will be close. Pick on price unless you need the 850W PSU.

Is the 30AGB10 worth the extra $154?

Only if you plan to upgrade the GPU later or need Wi-Fi 6E. The 850W PSU and confirmed wireless are the real differences; otherwise the Gen 10 saves you money.

Which has more storage?

The Gen 10 lists 2TB of storage versus 1TB on the 30AGB10. That is the clearest spec advantage for the cheaper machine.

Can I upgrade either one?

The 30AGB10 is the safer bet, with a confirmed 850W PSU and room for a larger graphics card. Reviewers describe the Gen 10 as not for the hobby builder.

Do both include Windows 11 Pro?

The 30AGB10 lists Windows 11 Pro. The Gen 10 listing only says Windows, so confirm the edition before you buy.

Neither has a stated warranty edge here. The 30AGB10's larger PSU gives it more room to stay useful as GPUs get hungrier.
