im just wondering how good it would be and what psu would i need for both (if they work together)
would a r9 270x work with another r9 280x?

It depends on what you mean by work together.
Crossfire will not work with these two cards together, so games cannot make use of both.
The second card could be used just to support additional monitors (not for games) or for floating point calculations (litecoin mining, scientific calculations, etc.)
For crossfire you would need two R9 270X cards or two R9 280X cards.
You would need a power supply with at least 750W on the combined +12V rails to power a 270X, 280X plus your CPU, etc.
You would also need four PCI-E power connectors.
Any good quality 850W power supply would do the job.
