Will My PC Handle an AMD Radeon HD 7770 1GB GDDR5

Hello, I just got a new PC and I was wondering if my PC could handle an AMD Radeon HD 7770 1GB GDDR5. My current GPU is a Nvidia GeForce GT620 1GB, not too great. My setup is:

CPU - AMD Athalon II X3 450 3.20GHz
GPU - Nvidia GeForce GT620 1GB(they sent the wrong GPU lucky me was suposed to be 520 XD)
Power - 350 watts

  1. Upgrade the PSU and the 7770 will work, You do need something better then that 350 watt to play it safe, Some will say it will work, but I am not sure what PSU they used in that system, so I can't tell what the AMPs are on the 12v rail.

    Can get this PSU or better http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026
  2. Yes your pc will handle hd 7770.just upgrade psu to good 400w above.
  3. I'm more concerned that your CPU may bottleneck your 7770 but I think that your PSU will be able to handle the card if it is a good PSU. Either way you can try the HD 7770 with your current setup, wont harm your computer.

    If you have a lower resolution(less than 1080p) moniter then your CPU shouldnot bottleneck your Graphics card
