Opera; If the motherboard as AGP video, you can find 128meg off name AGP 4x/8x cards for as little as $25. If PCI-E, then barebones 64meg cards are around $40 (most of those cards have some sort of software trick that snags system memory if you push your card with high res textures and whatnot, but so long as you are talking about simple display, this trick never comes into play). Pricewatch.com is a good place to find the discontinued but still adequate cards.
