Mate thanks about the question i asked an IT programmer and he Say the power between cpu and gpu is about 5fps not big deal.No. That's a pretty weak GPU. I'd recommend something better if you're using it for games. If you're not using it for games, use the CPU graphics.
I already bought that all the games are working smooth and btw that it person its my friend and thebottlenecker site its garbageThat sentence is incomprehensible. No idea what you're trying to say.
If your budget only affords an R7-250 just wait and save more money. That card isn't worth buying these days. Trust me. You're wasting your money.
