I have this cpu AMD A10-5800K Trinity 3.8GH and this mobo ASRock FM2A75 Pro4-M FM2 AMD A75. With 12gigs ram. Is it even worth getting a new gpu or making something else better for the money?
The 5800K can handle any current GPU without much issues. What is your GPU budget?
Is there a way I can cross fire the built in Gpu with an off board gpu?
It only works for select titles, performance can vary and even underperform sometimes if the game isn't optimized, in short, it's more trouble than it's worth.
