I have now a GeForce GTS 250(1 GB with 256 bit memory bus DX10) and i want to play Battlefield 4 (multiplayer) but the game shutters a lot and when i play i have very but very low fps so its almost very hard to play it!! i tried to find a cheap GPU because i don't want to spend much on this, i found the GeForce GT610 2GB LP (2GB with 64 bit memory bus DX11), currently this GPU costs 50 euro in Greece so i thought this will be good buy but when i asked a friend told me that the memory bus is very low and GT610 will not make any difference and its actually worst than i have now!! the question is : does memory bus have much of a difference?
