I want to get the most out of my graphics performance from my system. I know it's fairly old and that's why I need help deciding which GPU upgrade to get. Please no answers like "You need to get a new motherboard or PC before getting a new GPU." I already know my mobo only supports PCI-E 1.0, so there's no point in buying a 3.0 card because it'll be bottlenecked and I own't get the most performance out of it. That's why I need to know which 1.0 card to get because anything is better than the current card I'm using for games. I need something that will let me at least play on medium to high graphic settings. Thank you all for your answers in advance.
