  1. Quality 450W will be enough.

    Have a look at this SeaSonic S12II Bronze 520 W. It's a bit too much, but current price with -15% code is great:

    first of all, get a h77 motherboard. z77 is useless to you. good one is the h77m from asrock for 69.99

    -get a i5 3470. i7s are useless to you in gaming
    -ddr3 doesnt run lower than 1066mhz. you most likely got some ddr2 ram
    -there are cheaper ram sticks around such as patriot viper 3 for 28.99 after MIR at newegg
    -use LED lights from bitfenix. much more balanced and brighter
    - you can use the money saved and get a xfx 7870 for 229.99 at newegg

    ty for the comment.. about the processor.. i transfer my old pc's cpu that is i7 2600 to my new pc( to save more money) about the ram stick you suggested..its not available in my country :/ meanwhile the xfx 7870, it too expensive in my country.. its like twice the price of hd 7770 :S

    buy really many thx for the comment.. but some ppl say that the psu watt should be higher :/ maybe 600w+?
  4. i didnt say anything about your ram. i just said that your stick of ram that runs at 665mhz wont work

    well then get a 7850. there is a massive increase in performance. the 7770 is like a last gen 6850

    sadly in my country the price still far much expensive for 7850 compare to 7770 :sweat: im from malaysia the average price for 7850 is around 750Rm 245USD meanwhile for 7770 470RM 153USD. . . almost 100 dollar in different.. im my country 100 dollar 350rm is quite alot :o

    about the ram... hehe thx for the tips :D i think i will just throw away my noob 4gb 6xx mhz ram :P so that i can use my DDR3 memory : :sol:
  6. how much is a 6870? thats a better option than the 7770
