Hi Piousson,  

Welcome to forum,

About your graphic card -  HD7870 -

Just be careful not to take more powerful. Otherwise it will be less well managed by the processor.

Just be careful to the power supply. Check the number of cables PCI-E 6-pin and 8-pin you have on the PSU.

Because HD7870 graphic cards generally needs two cables PCI-E 6-pin. Sometimes one 6 pin and one 8-pin. Rarely 2 of 8 pins.

Otherwise, there are adapters for PCI-E cable.

Check on web site like:

Otherwise, if you prefer HD7850, I find two models - use only one PCI-E 6pins Only.

But it seems slower than the Sapphire. Check Specs.

You have a PSU ODIN GT 800Watt

It is necessary take into account not only the wattage, but the amperage.

I check your psu... your are fine...

I hope this information is helpful.
