hello guys, my system specs are,
Sparkle Nvidia Geforce 550ti 1gb DDR5 graphics card
Intel i5-3450 3.1 ghz
Intel DH67BL
corsair vengeance ddr3 4*2 ram
samsung 22" LED full hd monitor
cooler master thunder 500w psu
my graphics card is having problems so i'm going to ask vendor to either replace it or give another one. Should i go for the same or should i ask him for HD7770? which one would be better? also tell me if i get HD7770 would it be necessary to change other parts?
rply asap. thanks!
