But like I said the phenom II 945 is faster than the phenom II 830, which is why the 945 system costs more.
For example, at bestbuy the DELL I5-560 systems are fetching higher prices than the DELL AMD 630 Quad systems, by nearly $300+
But I think I get your point overall, you've noticed that newer processors, although less/equal or a bit faster than older systems are costing much higher than they should? Kinda to be expected though. Still $300 with all else equal in those two computers is very high.
My use for the computer I'm buying is Office work and making small Magazines. My bottleneck seems to be how fast the printer can process not the computer.
lol guess it's time for a laser printer if you don't already have one
