Sorry for the terribly bad english.

Hi guys! Atm im ''gameing'' with a pretty old pc and I was like: Man i should upgrade,there's a lot of game i can't play! So right now I got this combo: Athlon 64x2 5000/Gigabyte Ga-Ma770_Ud3/4gb ram/9600Gt 512mb I would like to upgrade only my cpu,motherboard and ram right now,later i'll get a better gpu. Is there any possible opcion which is ''cheap'' and give a great performance boost? I'm very low on money Sadlife
