Very nice parts. , Except Motherboard and processor , I would get E8400 will last you longer then +5400.... , U can OC the E8400 to 4.0ghz EASILY. , +5400 @ 3.4ghz wont be easy.

Motherboard - http://www.newegg.com/Product/Produc...7&Tpk=gigabyte

processor - http://www.newegg.com/Product/Produc...82E16819115037

OS - You need OS of course... WIndow vista 64-bit SP1 http://www.newegg.com/Product/Produc...82E16832116488
I would choose a single 4870. , if u game at HIGHHHHHHHH resolution get a 4870x2

You can even buy a 8800gt.. or 4850... under $199 , but MMORPG is big , if u wanna play all max with aa ,af you gonna need 4870x2.... for decent fps but i suggest waiting so get 8800gt or 4850.!

Have fun with it , your luckyyyyyy i had to work to buy my PC by saving up!
