Its a Little more involved then adding tons of ram. I'm no expert for sure, but what i do know from years of experience and pissing off money on parts that now sit in a file cabnet, waiting to be collecter items.
Its more like the type ram your using (66mhz, 100mhz or 400mhz ddr duel channel etc.). Your mother board type (bus size, type ram support, video slots pci or agp 1x or 8x etc.) , your cpu ( how fast , bus size, how new , etc..), sound card( type, brand, and the compatibilty ..) Video card (not so much how new it is or amount of ram it has) , but type ram , pci or agp, what settings the video card maker supplies you in display settings. Some have more then others, you should not have to "over clock" any video card if your computer parts jive.
The thing to remember is the games of today are becoming more and more demanding, online gaming as well as store bought games. You want decient graphics and more then Pong style games. And if Ya want to GAME as a HOBBY, you Must upgrade your tools to do so, and upgrade as a whole .
Think of it like this, (guy talk

) a stock 426 hemi motor is no where near as fast as a built 426 hemi, But you also have to buy the correct matching parts for the built hemi or its just as slow or slower as a stock hemi. ei.. big tunnel ram and two carbs without the cam and head work is just gunna slow you down and make for disappointment in the end.
So its all about what and how you mix the ingredients that makes for a good computer to get the performance your wanting. Dont blame the game if you run 87 octane when you really need 104 racing fuel.
