I'm upgrading from an i5-10400 and RX 570 system that now struggles with games like Fortnite and Call of Duty, even at very low settings. I'd like a new AM5-based build with performance around or above a PS5 and a good future upgrade path, but my current parts list is over a CAD$2,000 budget. The proposed system uses a Ryzen 7 7800X3D, B650 motherboard, 32GB of DDR5-6000 memory, a modern midrange graphics card, and a 750W power supply. What parts could I replace with less expensive alternatives without sacrificing too much gaming performance or upgradeability? Could a cheaper AM5 processor work? I'd also like to know whether the new system can outperform a PS5, whether I can reuse my Corsair Carbide 175R case and existing SSDs and hard drive, and which Canadian retailers may offer better prices than Amazon. I'm located in British Columbia and would also consider buying used parts locally.

That graphics card should comfortably outperform a PS5, particularly at higher frame rates or competitive settings, although the exact result depends on the game, resolution, and graphics settings. Your Corsair 175R is a standard ATX mid-tower, so it should fit the motherboard, dual-tower cooler, graphics card, and new power supply as long as the card’s length and cooler height are within the case limits. The existing SSD and HDD can also be reused; just make sure to back up your files and consider a fresh operating-system installation if the old drive contains Windows.
The biggest easy saving is replacing the Ryzen 7 7800X3D with a Ryzen 5 7600 or 7600X. It can save more than CAD$200 while still delivering excellent performance in Fortnite, Call of Duty, and other competitive games. Since it uses the same AM5 platform, you can upgrade to a faster processor later without replacing the motherboard and memory. Also check for CPU, motherboard, and RAM bundles, which are often much cheaper than buying each part separately.
Thanks, I’ll compare those processors and look for bundle deals before ordering.

For Canadian pricing, check Memory Express, Canada Computers, and Newegg in addition to Amazon. Set the parts list to Canada so regional prices and retailers are compared accurately, and watch for local bundle promotions.
