hehe, depends wether u like the rts games im a big rts gamer, with ur system i recommend Sup Com (Supreme Commander), bloody brilliant rts ^^ DoW (Dawn of War) is also good but gets boring after a while. btw Red Alert 2 sucks
Don't get Call Of Duty, get Command And Conquer 3: Tiberium Wars that game will really blow you away ^_^.
just bought command and conquer myself. seems decent. the graphics are ehh(damned xbox 360 killed my graphics, hate it when they make a cross platform game and the PS3/xbox being included result in dumbed down visuals) but game play seems fairly good
NO !!! dont get CnC3, its terrible, gameplay is shot and the multiplayer is absolutly ----, u have to dload some rubbish client in order to play it online, and all the peeps do online is spam the hell out of u, also i dont know if theve fixed it, but the only way i could dload patchs for the game was to get them manually, and the lazy ass developers dont post the manual patch untill 2 or so days after the patches release >_< dun get CnC3 ^_^ Edit: and annother word of advice, dont ever buy a game from EA ... ive learnt that the hard way ...
