Hello guys, i want to ask you something, i found a good gpu (gtx560 1gb ddr5 256bit) which i can buy cheap , but the problem is that my pc is low end 4gb ddr2 ram and amd athlon 64 x2 (if im not mistaken) 2.20ghz, so if i put this thing on it, can it harm the pc somehow (too powerfull to handle) and should i need any other stuff? or maybe i should buy a little bit less powerfull gpu, i want to play mid range games on low-mid settings.
