Ive yet to see a game running smooth with an onboard soundcard, they always cause a bit of lag in games, especially the high end games like doom3 etc, they just cant cope with the traffic being sent to them since they are in software mode and not hardware like PCI cards.


Your memory is fine, but I know Bloodlines was a bit laggy anyways for me, but only if I played it for more than 2hrs then Virtual memory started to kick in more and eventually the game got very laggy. But it shouldnt lag so much from start.

Other things you can try is turning down the GFX a bit, not a high resolution etc.


Also Your GPU it may overheat, later Nvidia cards had a habit of this, you can put on a small fan on it, about 30mm'ish (thats 3 cm :P) and that could help cool it down.


But I would even try with an old PCI sound card just to try it out before buying one, if you see a performance boost doing that then go get one, the SB Live! 24bit is reasonably priced (but lacks the gameport since controllers are coming more and more with USB connections)
