7750 is more power efficient over 5670 so go for 7750. did i say 7750?
Currently I'm running this
2 Sata HDD,
1 sata DVD writer
Core2Duo E7500 2.93GHz
2 DDR2 Sticks
I have local SMPS of Frontech which says it is a 450Watt but I dont think it can maintain atleast 50% efficiency.
Is it safe to use HD7750 replacing 9500GT????
