Which is best for me: Radeon 4550, 5450, or 5570?

I have had my pc for a few months using the intel integrated graphics and would like to upgrade a little to play some light games, nothing crazy. I have the following specs and would like everyone's professional opinion! I really don't know how to upgrade my power supply, so I prefer leave my machine as is and get something that will work for it with the current psu.
I need a low profile card, pci-e

Which of the cards above, Radeon 4550, 5450, or 5570 would be best for me? Can I run any of them or should I stick with the Intel HD graphics?

Lenovo H320
Processor Intel® Core™ i3-540 (3.06GHz, 4MB L2, 1333Mhz FSB)

That's all the info I have, thanks for your help!!

  1. I would upgrade the PSU before you add any graphics card. A 5670 is really the cheapest gaming card as well, what games did you want to play?
  2. I have a 21.5 inch 1080p monitor. I don't mind changing the psu if i can and it isn't too hard. Do you think i could run a 5570 now? I just want to play wow lotro or some older games. Nothing crazy and it doesn't have to be high res just decent fps.

    the case is so small that the psu will likely be smaller than standard atx unit, so finding a replacement might be a bit more difficult...

    5570 uses up to 50W (in furmark, 37W in 'games'), though the power color one uses a little less

    5450 maxes out at 13W, and 4550 at 19W

    They should all work with the current psu, just dont run furmark and prime95 at the same time on it and you should be just fine :P

    And unless it wasnt clear, the 5570 has the most oomph, you could even play some games with it. :D
  4. agreed. a 5570 should be ok as the rest of your system is fairly power conservative. The power supply brand FSP is generally good quality too. Is it a low profile pc? if so the best gfx card you can put in it is a 5750 (hard to come by but there is a low profile version of this card. this article will be of great help to you http://www.tomshardware.com/reviews/home-theater-pc-half-height-radeon-hd-5750,2804.html
  5. Thanks for the help! I will probably go with the 5570, because it seems to have a little bit of graphic power and should not fry my system, haha. Thanks again to everyone for the advice, this is cool place!!

  6. 5570 seems pretty questionable for a 180W PSU. It's also going to be dumping 40W into that little case.
  7. as per my link 150w is about his expected max useage from the wall. assume 80% efficiency and your down to much less than his psu is capable of producing. Should be ok. But yeah, make sure you have at least 1 exhaust fan to prevent heat buildup.
  8. yes there is a 5570 ddr5. its much better than the ddr3 version
