The Good

  • Inexpensive.
  • Quiet.
  • Low power. The box recommends a 350Watt power supply, but it runs overclocked on a 275W PSU!
  • Low profile.
  • Easy to overclock using the include ATI Overdrive software.

The Bad

  • Runs quite hot (due to passive cooling) at around 72C at full load.
  • Not very powerful, gives a Windows (7) experience index of 3.8 for aero and 5.8 for gaming, but overclocking easily brings those numbers to 5.0 and 6.3 respectively.


This is a great card unless you're an intensive gamer. Of course, the Radeon HD 5450 will play most mainstream games quite well! Company of Heroes, the Sims 2, Fable : The Lost Chapter, Spore, etc. will run marvelously when compared to integrated graphics. Yet, don't expect 100 FPS on Crysis. This is the card for you if you're looking to upgrade a cheap, lousy integrated chipset, or to build the ultimate home theater PC. We give it a 9.5 out of ten because it does marvelously what it's designed for, but more memory would have been a plus.
