I have a Dell Vostro 200 with a 300w PSU and an Intel e4600. I will upgrade my PSU if needed but I really would like to keep my current build. I want to use a GTX card for Nvidia Shield streaming. I want to play PlanetSide 2 with about 50 fps if possible at 1440p. This may sound unreasonable but I'm only 14 and money doesn't grow on trees.
