Hello, Please help me build PCs that will use A4-3400 without discrete graphics. I will use this in computer shop open almost 24/7 so efficiency, price, and performance must be considered. (best PSU?) It will not be for demanding games such as METRO 2033 or Crysis. PC purpose: web browsing, watch online(youtube and others alike), office application(MS word, excel, etc.), and gaming. (1366x768, low to mid settings) Games I plan to play are: >Casual games >LAN and Online games: Special Force, DOTA, HON, Rohan, Zhu Xian Online, Grand Chase, Cabal Online, Perfect World, Dragonest, Allods, Lucent Heart, Karma, Pandora Saga, KOS, Crazy Cart, Flyff, RFonline, and silk road online. Store I'm planning to buy is http://pcx.com.ph/ I live in Manila, Philippines. If you have any other suggested store near to my place, please let me know. Thank you in advance.
