You can install theRadeon  HD6570 without any problem

The only processors that have motherboard  BIOS support (that means compatibility) are the following:

• Intel Core i7-8xx (Lynnfield core)

• Intel Core i5-7xx (Lynnfield core)

• Intel Core i5-6xx (Clarkdale core)

• Intel Core i3-5xx (Clarkdale core)
  Installing the  i5-2500k is a no-go. Sorry.

Hi,

The AMD 6570 is not a high performance video card.

Review the ATI performance specifications. Look at the memory bandwidth specifications and the DirectX level support.

Most video cards will require a bigger power supply since the power supply in your PC is only 250 watts.

The newer modern games will require a video card in the 6850 or higher range depending on game settings.

Big_Dave is correct.

I do not recommend the HD6570 as a gaming video card. It will crash in games that demand high end video when you try to run them in Ultra High graphics mode.

Be aware that the card has a minimum 400 W PSU requirement. Your desktop PC  was delivered with only a 250 Watts PSU. You will have to upgrade your PSU if you want to use the card you asked about.

I recommend an OCZ or Corsair 450 Watt or larger capacity PSU.

 That means that your PSU must have at least one six-pin PCI Express power connector. To be on the safe side I would recommend a PSU that has two six-pin PCI Express poer conectors.
