The performance just isn’t there to allow you to increase your in-game settings to the levels that 512MB of RAM will help you. We looked closely at the latest games like BioShock, Lost Planet and Lord of the Rings Online. We know these games benefit from more RAM, but at the levels we had to play them at on the GeForce 8600 GTS that isn’t the case. You have to run these games at their highest in-game settings in order to experience the benefits of greater RAM on your video card. The GeForce 8600 GTS GPU simply does not have enough horsepower to pull that off.
