lol 1500 dollars would get you an i7 rig beefed up,but for your needs you won't have to spend that much money at all. Luckily for you ,there is a lot of options out there and the games you listed are not graphically demanding, I am always conscious of my budget so i don't like to waste money on hardware just for bragging rights, in your shoes i would go with an am 3 mobo, a 720 BE, 4 gigs of ddr 3 ram (1333 mhz), a 500 gb hdd or higher, something greater than 500 watts as my psu and a 4870. Such system would be a good multi tasker,great over clocker,and good gaming machine and offer some future proofness as well....now if you are an intel person i would probably go with the i5, a cheap p55 mobo, 4 gb of ram and still a 4870. None of the games you listed is graphically demanding enough to go beyond a 4870 and even the most demanding games can be played on high with a 4870 as long as you game at or beloe 1920x1200 resolution. Personally i would go with the amd build it makes more sense financially as it gives you the best value for what you do, but if you can spend up to 1500 dollars and dont mind spending it then a nice i5 rig with perhaps a 4890 (i wouldn't see the point) wouldn't be a bad idea it really depends. Your needs could be easily met and surpassed by the amd build i gave you but the i5 gives you bragging rights i suppose.
