Hi. I am using a Compaq SR5113WM. I just removed my edition of Vista and replaced it with XP SP3 so as to use less memory, and I just started playing WoW. I'm buying 4 more Gigs of RAM, and I'm wondering if I should also add on a graphics card. I don't know much about graphics and processors, etc. Any advice or recommendations would be appreciated. I know it'll play WoW as is, but it plays choppily unless I use the lowest graphics settings. I'd also like to get it up to maybe Oblivion proportions. Sorry for my vagueness. Thanks.
