500 or lower gaming build

Approximate Purchase Date: 11/23-24 day of /after black friday

Budget Range: No more than 500 with shipping included, I plan to upgrade parts little by little afterwards

System Usage from Most to Least Important: Mainly for gaming, nothing too serious just GW2 and WoW MoP. I may try others depending on how well the build handles. Other then that i'll stream movies and use it for music. Not too much.

Are you buying a monitor: No

Parts to Upgrade: Need a complete build, was using a laptop but it crapped out on me last week.

Do you need to buy OS: OS does not need to be added to the setup

Preferred Website(s) for Parts: newegg/amazon

Location: City, State/Region, Country - New Britain, Connecticut

Parts Preferences: Not too knowledgeable with computer parts, but I know Intel performs better than AMD. So Intel if possible

Overclocking: Possibly, although i know next to nothing about OC'ing

SLI or Crossfire: SLI

Your Monitor Resolution: I will be using an HDMI to a 51 inch plasma 1920x1080

Additional Comments: Im not too picky, open to all comments and info thats given to me. I know im not working with a huge budget, but thats all i can spend right now. As stated earlier im mainly looking to play Guild Wars 2 and WoW MoP. If possible i'd greatly enjoy a set up that would allow me to play with Ultra settings, of course with AA turned off or low, and shadow quality turned down also. Any advice/builds would be really appreciated. I've been looking around for a few weeks but with not much knowledge to go off of i always second guess anything i find. Thank you in advance, enjoy the holidays!
