Could not find an AMD Radeon RX 470ti, but if you verify you have a 6-pin graphics power connector from your PC power supply, you can fit an RX 470 into the G5 5090.
Here is the system specs https://www.dell.com/support/manuals/en-us/g-series-5090-desktop/g5-5090-setup-and-specifications/video?guid=guid-08325430-cdb4-49e7-864f-dda1f14e7905&lang=en-us

Assuming you meant a 4070Ti...
NVidia recommends a minimum 700W PSU for the RTX 4070Ti. The G5 5090 has either a stock 360W or 460W PSU. So you'd need an "after-market" PSU that fits inside the case. Read this entire thread carefully...
The RTX 4070Ti supports PCI-e 4, but the G5 5090 only supports up to PCI-e 3. The card should be backward compatible with PCI-e 3, but performance won't be as good as when used in a PC supporting PCI-e 4.
You'd also have to check the size and width (number of slots) for the specific card you'd want because NVidia says the dimensions vary by manufacturer. From the look of the motherboard, a GPU that takes up 3 slots could block the PCI-e x1 slot, if that matters to you.
You can check userbenchmark for G5 5090 configs to see what GPUs others are using. I see a couple of reports for the 4070 (not 4070 Ti) that say "poor" or "below average". And keep in mind that site doesn't include size of PSU installed in the PC, so just because someone is using a certain GPU doesn't mean it works with the 460W stock G5 5090 PSU.
