ive been playing on rct3 and gta sa lately on my pc (check sig) ... i cant remember if i put my graphics card in there but ive attatched a pic. rct3 is on quite low settings and still runs slow. its still playable but it isnt that impressive, its not that new either (the game, my pc should run it fine), SA is also on the lowest setting and isnt as bad but still lags a lot sometimes and this also produces a crackling sound from my speakers (i made a thread on this but i dont think its to do with my router like someone said). any ideas what it could be... oh i downloaded the ceasar 4 demo and that runs ok on my pc but is a bit slow but thats a new game.
