  1. You are going to be limited with your power supply. According to Geforce.com, your current GTS 450 requires a 400 watt power supply. The best card from the current generation that matches that requirement is the GTX 650 Ti. The next step up, the GTX 650 Ti Boost requires a 450 watt power supply, so the non-Boost version is your limit.

    It looks like there is about a 30% performance increase you could expect by jumping up to an inexpensive GTX 650 Ti.

  2. The best Nvidia card you could add safely would be the gtx 650. You would have to make sure and connect the molex to PCI express connector to the card. Really the best card for your PC would be the radeon 7750 because it uses a little bit less power and does not have a PCI express auxiliary connector and it is a little bit cheaper.

  3. Nothing better than the GTS 450. I'm surprised it's even running on a 300W power supply, frankly, since the recommended amount is 400W, and the power supply is most likely not very quality.
  4. All of the cards mentioned don't need a 400 watt power supply but it is recommended. After entering your specs in a psu calculator you need less than 300 watts for the gtx 650 and the radeon 7750, but if your power supply is cheap and doesn't run very efficient you may run into problems down the road as your system gets older, or possibly right away if used for long hours of gaming.

    That's what I'm saying.
  6. Time to stop recommending the 7750.... it has the same performance as the GTS 450. Be sure to recognize the difference between a GTX 650 non-Ti and a GTX 650 Ti, which is about 20%.

    If you can run a GTS 450 on your current power supply, then you can run a GTX 650 Ti.
  7. Since you said you have a 400 watt PSU, change the PSU and put a gtx 660 in your machine. It might be a little bit of a bottleneck but you can do it and it's a powerful card and a good value.
