Hi,i can run Gta series in software mode only.in hardware mode it lags like hell.so yeah u can run them in software mode,if u don't care about high resolution & nice graphics.if i can run those games in software mode,u can surely run them @ 40-50 fps i think.i'm only getting 30-35 fps btw & u can only run them in software mode,because u have same graphic card as mine
