For suggestion on GPU u need to provide the following details,
i) Size of the monitor.(Preferred gaming resolution)
ii) PSU that ur friend uses.
iii) Games that he plays.
Is it a new build or an upgrade? Also if later then when? PC market changes everyday and this months best buy product may not be the best around next month. So its better to ask for suggestions when you are actually gonna buy it.
