i need some help from experts, do you think this system is enough to handle WOW if not in the extreme settings.
i am not really a familiar with build system this is my first attempt. what else do i need for the system to be operational
wireless card, sound card etc. need some good suggestions for what buy.
What daship said. Looks good overall, no questionable manufacturers creeping in there.
Make sure you grab yourself some high-quality thermal paste, since you're getting an S1283 I'm guessing you care about cooling... it'd be horrible if you ruined that by using the terrible stock goop
Also - just a note for after it's built, WoW will still have slowdowns. It slows down on my rig (see my signature), it's just because of how the game is made. It's not exactly that well optimised, especially with the graphics updates that Wrath brought in, they were introduced on an already outdated graphics engine.
I'd have to say for WoW, this is extreme overkill. The vid card and PSU especially. Kraynor is correct with the engine being older, I'd say that a 3870 could max the graphics configured correctly. I wouldn't go buying a 3870, but the point of it. A $100 vid card like a 4850 or 250GTS would be more than enough.
ALSO!!!!!!!!!!!!!!!!!!! That mobo needs DDR3 Ram!!!!!!!!!!!!!!! The ddr2 you have linked won't work.
As for sound card, you won't need one. The onboard sound uses just a tiny bit of processor power, but the X3 won't even bat an eye at it. The wireless card is up to you and how you have your home network set up. If you are placing the desktop near your router, then just use a cable to connect it to the router. That's more reliable anyway.
If you are building for mmorpg speed, Id suggest swapping the hard drives for a ssd raid setup or at least running your mmorpgs on a single SSD drive - expensive but very worthwhile in mmorpgs. One of the things that causes slow downs in mmorpgs is seek time on mechanical hard drives. With traditional single player games devs can optimize loading of textures to suit the current level - They KNOW what textures to expect in what area, but in an mmorpg you can have any player texture at any location meaning its next to impossible to prefetch player textures. Seek time may not sound like much of a factor, but you just have to consider how many textures each player represents maybe 14 or more textures so thats 14x your seek time at least for each individual player, if you have 10 players in an area thats at least 140x your seek time, its easy to see how 20-30 players can cause a few seconds of slow down by themselves! Its not the size of the textures its the seek time to each and every texture This is one of the reasons defrags can help on mmorpgs. However a raid 0 SSD setup will have more impact on these sort of population situations than any amount of GPU power.
My wife and I have "his and hers rigs", identical in every way except I run my mmorpgs on a single SSD drive, she runs hers off a raid 0 with traditional drives when running the same settings, in the same locations at the same time her system slows down FAR more than mine in busy population areas, if you pay attention you can see the hard disk light going mad during these busy populated areas when getting slow downs.
