Your biggest problem here, aside from potentially iffy PSU wattage (which might make upgrading difficult), is the video card. Be warned that it's extremely weak and almost non-gaming-worthy. So yes, that will be bottleneck #1 - if you can get a stronger video card with it, things will be looking up. It's still not really a powerhouse and, personally, I would suggest budgeting more like $800-900 for this kind of purchase if you want to do games. It'll last you much longer as a result. So I'm not sure whether $468 + the cost of another used video card will be really worth the effort here when for even a couple of hundred bucks more you could have a much more solid system built...
