Lets see, i think this is the best you can do with the money: Cpu: amd phenom 2 x6 1055t @2.8 ghz [ turbo mode when less cores are used than 6] (about €150,-), you could get an intel but for gaming amd has best value. Ram: 2x 2gb ddr3 1333 mhz cl9 (€50,- kit) Graphics: HD6850 (€150) i got bad experience with nvidia. Motherboard: asrock m3n78d (€50,-), if this mb isnt in your country, just look at the specs and see if the processor is supported. Case: take one that supports atx, rest is your choice. (around €45) Hdd: seagate barracuda 1tb (€50) Power supply: cooler master 500 watt or more. ( €55) Dvd-drive: any brand will do (€30) Monitor: samsung syncmaster 22 inch like the P2270H(€150) Mouse: logitech mx518(€30) Keyboard: Buy some cheap one (€10) Headset: creative fatality headset (€30) Total: €800,- I took the prices from holland so to be honest it could be more expensive in greece. :S
