I need a decent graphics card, because the mmorpgs that im playing atm are lagging and i need to reduce the resolution and other things in order to play. Ive been using the same graphics card that my computer came with 4 years ago >.>. So does anybody know of a good decent graphics card that i can buy that isnt too expensive? Oh and also since this is my first time with a graphics card can you guys explain the basics, and how do you install the new graphics card and take out the old oneo.0?
