[H] I5 I7 ??

[Winterlight]

My 2nd PCs motherboard has apparently died so I am looking at a 
upgrade, motherboard, ram and CPU. The I5 is the cheapest at 200 but 
there is a 800 series I7 for 80 bucks more... why wouldn't I want to 
go with the I7>

It is getting so you need to take a class to figure out Intel /AMD CPU lines.
