[Khandaker]

Hello great people of the internet! I have a dell vostro 200 (mini tower) it has a power supply of about 300.
Here are the specs for it:

Processor: Intel(r) Core(tm) 2 duo cpu E7300 @ 2.66Ghz
Memory(RAM): 3.00 gb

Name any graphics card that will work! from ($60-anything)
Im not a hardcore gamer or anything. I want to run my Minecraft faster, and play some games from steam here and there like combat arms and black light retribution. (Maybe even Arma 2)

Thank you

My budget isnt top notch, but name the best possible graphics card anyway. Im aiming for somewhere around $60-$80 remember, im not a pc gamer, i just want to play casual games from time to time
