good enough to run games such as DayZ? It is the best possible choice for my inspiron 560's power supply (which is 300w). I am not planning on upgrading my PSU or getting a new computer though I know I can. I just want to know if this card will be good enough to run modern games until I can get a new PC or power supply.
Any answers with information would be greatly appreciated.
Your best possible choice to run on 300watts is HD7750! The 6570 should work though in game settings based on resolution.
But are you sure that will be ok on 300w at load? The recommended PSU for that card is 400w.
Yes I am sure because the card typically maxes out at 43 watts and the rest of the system around 150 watts so max system load is just +/- 200 watts.
The manufacturers recommendation is always Higher than actual since there are many crap PSU's on the market and protection against liability!
