Hey everyone. I have been out of the PC world a long time so I need some help on a up and coming build that I am doing. The background of the build is to play games and heavy computing, such as running multiple networking clients and VmWare Clients. I am no Extreme gamer or anything, but I do like pretty pixels. I play a lot of Call of Duty, Steam Games, and World of Warcraft. I know its a old game but the graphics can be crushed when settings are on high and your in a 25 man raid... Thats the basics of the work of the computer, I do a lot of my actual work on a Mac.... I am wondering that my current PSU a Antec Neo 650w is capable to handle this system with zero Over clocks. Motherboard: ASUS M4A77TD Video Card: Sapphire 4870 CPU: PhenomII X4 955 Memory: 2x Crucial DDR3 1066 HDD: Western Digital Caviar 1TB DVD Drive: Asus DRW CPU Cooler: Corsair Cooling Hydro Liquid Cooling And I am anal on cooling so I will have a fan running in every spot where they can fit. So it needs to also support a fan controller, and 5-10 fans. And I will be bringing over 2-3 hard drives from my current computer also.
