Which System Is Better?

[dannyp1]

I still get a little confused when comparing dos systems.  Which would be a faster, better computer/processor?

1.  An older (maybe 5 to 7 Y.O.) system with a 2.52ghz processor?

2.  A 3 year old system with an Intel Core 2 Duo 1.80ghz?

Number 1 is what I use daily.  Number 2 is being offered to me by someone moving at a hard to resist price.

OK, here is what is being offered to me for $200

20" Samsung Syncmaster monitor 205bw

Tower-

2 gigs ram
ASRock 775Dual Motherboard
MSI 8600 graphics card
Intel Core 2 Duo 1.80ghz
2 hard drives - 32gig & 320gig
USB Wireless wifi receiver
DVD Burner
Windows 7
Microsoft wireless mouse
Microsoft wireless keyboard

I think that's most everything.

Is the price way out of line because this is double the $100 amount.

I should have been clearer.  I am talking about windos systems.  The P4 system has XP and the core has 7.
