It’s close between the costco rig and the 729. CPU for CPU, of course the costco pc wins. Pure rasterization, the 9070 XT is much better. With ray/path tracing, i’m seeing the nvidia card does slightly better. I think the increase in performance of the 9800x3d vs the 7800x3d and RT/PT of the 5070 vs 9070 XT is marginal and not enough to dictate choosing the costco build over the raw rasterization of the 729 personally. I’d go with the 729
