yea the 7770 wont cut it even for basic gaming, firstly build it yourself, secondly try to see if you can fit a 7850/7870 in there. If you dont do much demanding stuff downgrade to an i3-2120 so you can afford the 7870
@angaddev i think 7770 is sufficient for my need, i play games that are 5 years or older. Unless i can get something better for the same money.
@deemo13 i understand 3570k is not needed if i'm not overclocking but like i said, i cant change the parts list. My friend is selling it as a package. Can you come up with another build with the same price just to compare?
