近排部老野機開始唔夠力,$$

先講下舊機配置

i5-760 oc 3.52G
display:sapphire 5850
mb:giga p55a -ud3

打算保留以下硬件:
ram: 8G *2 (kingston) +4G*2 (a data)
SSD: crucial 250G
HDD: WD 3T *3 (raid 5)
power: Corsair HX650
ATX箱一個

睇緊邊隻升級plan好
plan 1:
ASUS B150M-A D3 ........hk$579
Intel Core i7-6700K........hk$2520
SAPPhiRE RX 480 NITRO 8GB...hk$2450

聽講6700k用普通ddr3會傷機,暫時手上既ram用1.33v 都跑到ddr3 -1600,
唔知o唔ok

plan 2:
Intel Core i7-4790K..hk$2490
GIGABYTE G1. Sniper B6--HK$740
XFX RX 480 GTR OC XXX..hk$2450

呢個combo有d舊 但係唔洗諗d ram 夾唔夾

都係預5~6千 upgrade,今次唔諗住oc啦, 買k版係想要高d default core

歡迎其他更好砌法,
請指教
