What is currently the best ~$150 videocard for people with case space and power supply concerns? I currently have a Dell XPS 730 with a stock power supply, and probably not enough room for a very long videocard.
It has a Dell i5 Core i5-2300 (2.8 Ghz). I'd obviously like something that is powerful, but not something that leaves me CPU bound. My main concerns are console ports at 1080p/60fps and emulation of 3D systems (Dreamcast, PS2, Wii). I don't really care about being able to run Battlefield or Skyrim or Crysis at insane settings. 1080p is important, but I'm really more interested in 60fps. Don't care that much about graphical effects.
I was considering getting some variant of the Geforce 750 Ti, but I'm thinking I might be able to bump it up to something better.
