I put him together a build just now and this is what i got for ~490.
antec 300 illusion case
asrock 970 extreme3 mobo
radeon hd 6770 (with 20 mail and rebate, deus ex and dirt3 game coupons)
team 8gb 240 pin ddr3 ram 1600 (pc3 12800) (comes with kaybles hdmi 6ft)
amd fx 4100 zambezi cpu (comes with 10 newegg promo code)
and im selling him my 400w psu for ~50 (includes price of me building it for him)
so how could i make this better for him? and i need to get rid of my 400w and i used to have this build with a different case, diff ram (1333 speed) and a 5770 (6770 is 5770 with LESS power consumption (so ive been told) so i think this should work.
