My girlfriend is looking to buy a new computer. She mainly uses it for internet and photoshop, not really into high graphic intense games. She also burns quite a few cd's / dvd's but doesn't need / want a blu-ray player/burner. I'm able to help her a little bit, but the part where I get confused is when they start talking about Duo core and Quad core. Some links I've seen have said "Quad core processor which gives you 9.8GHz". But I was under the assumption that all duo/quad core was is basically either 2 or 4 "highways" on that one processor? so a 2.8GHz would only be 2.8 but... now I'm confusing myself again.

She's picked out these two. Can someone maybe take a look and tell me which they believe to be a better deal? She wants a fairly good computer so she can upgrade it in the future if she wants to.

Thanks:

Computer 1
Computer 2

Of the 2 computers , if $ isn't a BIG factor I'd go with the quad core .
Although it is a little over kill for what you said the computer is going to be used for it has the newer technology & [IMO] the better components.

Dual & quad core processors do not run in tandem to make a faster CPU.
A dual core 2.5GHz CPU does not run at 5GHz.
What it does do is split the load between the 2 CPU's so 1 CPU isn't doing all of the work.

In order for a program to really take advantage of multicore CPU's it has to be written [encoded] to run on multiple CPU's simotaniously .
If it isn't written specifically to do that it is still only going to run on 1 CPU at it's given speed no matter how many "cores" it has.

The advantage is that if you have 2 "cores" the load isn't all on 1.
One core can be running Windows & another a program .
By doing that the computer is faster simply because each CPU [or core] doesn't have to do as much.

The biggest caveat with multi core CPU's is the CPU technology is far ahead of the software technology.
As it is there aren't a lot of programs currently encoded to take full advantage of the multi core technology but that will change .

Just opinion...but I would never consider purchasing a PC on eBay.

I see no mention of warranty, no mention of operating system CD...what happens when things go wrong (as they surely will)? Not to mention the fact that the system speed is misleading in the ads.

I don't own any boxmaker (Dell, HP, eMachines, etc.) systems...but I would surely go that route before I ever expended my money for a system which fails to even mention support responsibility, warranty, or provide the capability for reinstalling the O/S.

The following is put forth for comparative purposes only:

Great, thanks for clearing that up for me.

On the Dell website, it says "Intel Core 2 Quad" and then it says "Intel Core 2 Quad-Core" What is the difference between these two?

As far as I know it's just 2 different ways of describing the same thing.

A Core 2 Quad is a quad core CPU.

A Core 2 Quad-Core is a quad core CPU .

The big difference is " Core 2 Quad-Core" is more specific about the CPU having 4 cores.

No difference, sloppy wording :thumbsup:.

Intel phrases it thusly, http://www.intel.com/products/processor/core2quad/index.htm
