What's the good of showing off anyway? PC is personal computer.. its for the specific person personal use only and that particular person have to right to buy whatever specs he think suite his or her own needs based on the usage. Not every PC user is a gamer... Some of us just use the PC to do some accounting, some Word/Excel documents or just some plain web surfing.. So respect others..

Anyway.. 2GB of RAM is the most optimized option.. 4GB currently will not boost your Windows XP .. unless you're planning for Windows Vista soon.. that is..
