I'm unlikely to spend more than 300ish, but was curious as to what my options were, even ones that exceeded my price range. An SSD is very tempting. I'm not clear on which newer graphics cards would be better than what I have now, and which would be more of sidegrades, though. Would a medium or low end, but newer graphics card necessarily be better than what I have now? Could I get, for instance, a graphics card that isn't particularly expensive, but clearly better than the one I have now, and ideally, more power efficient?
