Upgrading from 3650 to 5770?

I'd like to replace my graphics card on my Dell Inspiron 546. It currently has a Radeon HD 3650, but I think about upgrading it to a 5770. Is this upgrade worth it? Take in mind that I'm a PC-gamer with a limited budget. I have a 300W PSU, but I've already did some calculating and that shouldn't be a problem

  1. HD 5770 is a good choice. But I really doubt that 300w PSU of yours can take it. It needs at least a good brand of 450w PSU with 1x 75w 6-pin connector. etc; seasonic, antec, corsair.

    I used this to calculate the PSU:
    http://extreme.outervision.com/PSUEngine

    It says it needs 293 (recommended) or 243 (minimum).
  3. 300 W is not enough for a 5770.

    You can try a 6670.

    +1 to Dominaz1. If u cant afford new PSU, then HD6670 is a good choice.
  5. Could you guys recommend a 450-500W PSU that would work?
  6. u can get any of these .their price is between 52-60USD
