Help with upgrade

[Scott24]

I have a emachine T1801. I have done a couple of things over the years to try to keep my computer some what up to date. I went from 164MB of ram to 512 and got a AGI video graphics card. I play World of Warcraft and it runs ok as is. But I wanna know what else can I do to get my computer to run this game better without burning my wallet? Also can my computer hold more then 512mb of ram or is that it's max? Is there anyway to change is max? Thanks for the help.

Well too make the Game go faster lower the Game Details and lower the resolution down in the Games Setting Menu:

The Higher The Res: The More Nice it looks the slower it runs
The Lower The Res: The More Less nicer it is and Runs faster
