The most powerful PC you could build in 2005 would have a 7800 GTX (AKA G70). Incidentally, that is the closest thing to PS3’s GPU, which was famously less powerful than 360’s. On the CPU side it’s harder to compare because of the different architectures, but it wouldn’t be matched (and exceeded) until 2006 with the Core 2 Duo processors.

You could have two of those GPUs in one PC. If you’re talking price vs performance it makes sense but the statement as stands is not accurate
Assuming you’re not CPU limited, what you’re doing scales with SLI and the drivers actually work, sure.
