Hello friends! I recently have been in doubt, due to in efficient performance in the games of 2013. Like Crysis 3, Tomb raider, Bioshock infinite etc. I tried updating drivers. But lowering the settings to MEDIUM details is the only solution to smooth gaming experience at 1080p. Considering the specifications i have. I would like to ask you fellows how much power will be sufficient but not a waste, if i want to invest in buying a BRONZE POWER SUPPLY. Also see this screen shot where Amperes in VRM cross 40 and sometimes reach 48a ! aside from the fact that 12v values drop from 11.90 to 11.78 or even 11.67 at times. Not too frequently. As in they are stable but they do ripple these values. http://img822.imageshack.us/img822/5411/forumwo.png * So the two questions i need to ask are: Q: how much wattage does my PC require while gaming at peak load with current hardware, even if i change my GPU from 5870 to a 7870 and core i3 to a corei5 . With nothing to overclock. Q: Do Amps on GPU VRM tell that our PSU needs this much ampere supply to let the hardware run EFFECTIVELY or this value has no relevance to a worried PC gamer in terms of performance dissatisfaction?
