I want a video card that is good value for money to replace my HD 4850. What is the best option? Here is my system specs:

Gigabyte G31m-ES2C motherobard

Intel Pentium Dual Core 2.5 GHz

4GB DDR2

450W power supply

    Go with HD6670 or HD5670 as they don't require any power connections besides the power they get from PCI-e socket..... Anything above these cards require minimum 500W

    I'm still unclear of your price range and the purpose of graphic card (Gaming, Video Editing).....

    AMD's HD6670 and HD5670 are both very decent cards for gaming however HD6670 tends to use less power (Electricity Saving) than HD5670

    use the above tool and calculate a suitable GPU.. It's more convenient than asking here! :) select a suitable card and research on internet whether it suits your needs!

    I've upgraded my computed 1 month ago and I bought 1 ATI RADEON 7750 1GB GDDR5 and it works very well. My power supply is a NOX URANO SX 500watts but the video cards supports 450 watts too.

    Igor, your CPU will actually be the bottleneck on a better video card.

    Your overall power supply requirements call for a 200-300 watt power supply. 430 watts greatly exceeds your needs. However, that's not a big deal. Over time, as power supplies age, they lose potency. Also, it's a good idea to operate at around half your supply's maximum output as it keeps it cooler and extends its lifespan.

    For the money, you are better off with a GT 430 with good RAM on it, like DDR3. You can get a more expensive graphics card, but it will be handicapped by the CPU. For most purposes, however, the CPU is good enough.

    Looking at the typical power usage under load of your old card, i suggest a new cards with more or less the same requirements: GTX 660 Ti, HD 7850 are slightly higher in power usage but almost in the same range. And maybe the best your PSU could handle.
    At the point of money an HD 7770/7750 or GTX 650 would be an good try (but those cards give just a minimalistic performance increase).
    If you need gaming performance a card like the HD 6850/6870 qould be a good way beetween price and performance

      Bottleneck anyone?

    The Wattage alone is not sufficient information, since the capability of the supply in terms of connections will be an important consideration.

    Whether the PSU has a PCI-E (PCI-Express/Graphics Card Supplementary Power Supply) cable or not will determine if some cards can be used or not, because they require more power than can be provided through the motherboard interface alone.

    Also the quality/efficiency of the PSU is a factor, since a lesser one might not be able to consistently provide power towards the upper limit of its maximum.

    You can choose to get HD 7750 as it doesn't requires connection to power supply i.e. to SMPS.So,your 450 W SMPS will work with it.You can also choose to get this from Asus or MSI which ever you choose to fit your budget.

    A couple of questions:
    What price range?
    Do you want it for gaming or just general use?
