Goto the EQII.com and there is additional information about system requirements. Your system looks good. However, keep in mind that 512 ram is for the system and 126 is for grahics. With that said, you'll have to tweek your game settings to get the most from what you have. For instance if your running windows XP and have it set to show all the nice eye candy and run additional program in the background it will really slow things down in the game. The more RAM, such as 1Gig, will reduce lag more consistently. The better the graphics, such as 512, which is expensive, your game will play smoother. Some cards are more realible. If you choose to up grade your system, which is easy, RAM is not that expensive to upgrade and often worth it. Graphic card are a matter of opinion and there is a huge selection, shop carfully. Just becuse they are expensive doesn't mean they are worth it. Most graphic cards have a bench test comparasion to one another. Consumer reports has a good list of how they compare in price and performance. Good luck!
