I just got vista a few days ago and discovered that my GeForce4 MX 4000 just isn't up to snuff for it. I'm running a Socket 754 K8mm-v MSI mobo, 1GB RAM, AMD Sempron 2800+, generic 350W PSU and of course, my woebegone GPU. I will be buying a new system in about a year, but I would like to install Vista on my current box. I think all I lack for a passable performance is a decent video card. I was looking on Newegg at some GeForce 6600s and such. Would those cards be good enough for me? (I have an AGP 8x slot, btw). I don't really want to spend more than 75$$ on a card that will be replaced in a year anyways.
