Answer 1

Intel Core Duo (product code 80539) consists of two cores on one die, a 2 MiB L2 cache shared by both cores, and an arbiter bus that controls both L2 cache and FSB access. Upcoming steppings of Core Duo processors will also include the ability to disable one core to conserve power.

CPU Speeds: 1.06 GHz to 2.33 GHz
FSB Speeds: 533 MT/s to 667 MT/s
Process:
(MOSFET channel length) 0.065 µm

The Intel Pentium Dual Core is a new brand of Intel Processor that first appeared in selected base model notebook computers from Dell , Acer, HP, and Toshiba in early 2007. These processors are identified by the model numbers T2060 or T2080, indicating it is related to the Intel Core family of processors and may be a variant of the Intel Core T2050 chip. Early research reveals the processor to be similar to Core processors but with only a 1MB L2 Cache, whereas Core processors feature 2MB caches.

It is not known why, after announcing the retirement of the Pentium brand name, Intel has brought it back, although Intel did announce possible plans to return the Pentium brand to the market as an alias for low cost Core 2 chips based on the Conroe-L architecture. The planned numbers for those processors to carry the Pentium brand were to be prefixed by the letter E, not T as the Pentium Dual Core uses.


Specifications
T2060
1.60GHz clock
T2080
1.73GHz clock
533MHz Front Side Bus (FSB)
1MB L2 cache (shared, meaning both cores use this single 1MB cache. This equates to 512kb per core)
65nm process

Answer 2

First of all Dell is giving you 3 junks
1) Dell wireless card. upgrade to Intel Wireless card. 30$
2) the sound card is junk upgrade to Sound Blaster card 25$
three) get the Intel Core duo 50$

Total $ 755.00 + tax that's the way Dell makes their deals.
If you want to save some money from Dell you have to play their game, saying you have a small selling business at home, then they'll drop the the price.
Go for business shopping do as I told you
That's the way Dell works
