based on the Price History this is a new $30 CAD price drop,

afaik PowerColor’s a reputable Taiwanese manufacturer and when considering the current GPU market this seems like a pretty good deal👍

For relevance: $720 USD approximately = $979 CAD as of April 16, 2024 @20:38 UTC

For best raw performance (rasterization):

• the 7900 XT is the better buy as it’s average performance beats the 4070 Ti.

For best Raytracing performance:

• the 4070 Ti is still the better buy.

For best overall price to performance comparison (when factoring in Windows & Linux):

• the 7900 XT makes the most sense:
  • Linux distros are close to parity due to Valve’s positive influence with the Steam deck which helped rally Linux driver+compatibility development (news provided below)
  • due to FOSS AMD drivers, AMD GPUs currently provides the best OS flexibility in comparison to NVIDIA’s proprietary drivers and current focus on AI technologies

• this would also save users $260 or $189 CAD (before tax) if a Windows Pro or Home license isn’t required.
  • As Windows 10 is EOL, pricing for W11 is used here
  • desktop Linux OS’s are free

Notable Disadvantages (within the same price class):

• PowerColor only provides a 2 year warranty for the 7900 XT
  whereas for the 4070 Ti:
  • Gigabyte provides a 4 year warranty
  • MSI provides a 3 year warranty
