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


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
