i read the sticky about video cards and i still don't know what to look for. my current card is a PCI express Radeon X300 128MB Video DVI. now i'm going to be hooking up a 20" wide screen lcd, and i intend to play a few games. i have a limited budget, under $200, and i'm just so confused about video cards. is mine good enough to run games? what do all the terms mean? i gather the chip is either ati or nvidia? and pci and agi or the slots? i always see numbers with x this and gt and have no idea what they mean. any help? thanks
