reccomendation for ram and graphics card? I need something cheap as my budget is tight.
Is it reccomended to overclock my pc?
I doubt you'll have much luck OCing that PC, your CPU ain't all that great and your mobo is most likely shitty as hell. I would probably recommend you just get 4GB of the same cheap ram to get a total of 8GB and you try getting a decent mid-range card. It would be awesome to know your budget about now, but if you're really short on cash I recommend you try looking for the older 5770 - even now it's a pretty powerful (albeit cheap) card that can even take on the 6770 and the likes. As they've all but gone out of regular sale you might be lucky to find a good second-hand one, which would further reduce the price. Otherwise, depending on your budget, the 6770, 6850, 560 Ti are all good cards for their price, though they are a bit costlier (~$110 for the 6770, ~$160 for the 6850 and ~$220 for the 560 Ti).
