Looking for a Laptop - this looks good but a bit cheap. Any comments please?? Thanks
well for a start its NOT 4ghz this person is 'playing dumb' as many do and multiplying a 2ghz core 2 duo by two so that they are saying its 4ghz not 2 cores each running at 2ghz..........
There are two sides to any question; MY side and the WRONG side (Winston Churchill)
Not your listing is it??
Trying to get more bids perhaps?
6 hrs to go, will the public bid more........or will the seller lose out with his clever $1 reserve?!
HOME-LianLi PC-9F,ASRock P67Pro3, i5 2500k @4Ghz, 8Gb HyperX, ASUS GTX660 OC, Corsair Force 120 SSD, HP zIPS22", HOME SERVER HP ML110G6 HOST-Plex\Ubuntu\8
The suspense is killing me ....

Core i5 2500k / 1 x 90GB Vertex 3 SSD / 1 x 250GB WD Black Laptop HDD / Radeon 6850 PCI-e / Creative Sound Blaster X-Fi Titanium PCI-e
Not cheap at all!
I'd like to ask about this 2 GHz/4 GHz argument. If you think of GHz as cycles per second (for simplicity's sake let's use two 1 Hz CPUs and assume that the system can perform one operation per cycle) then the system as a whole would surely still accomplish two operations per second and therefore be equivalent to 2 Hz (or in the case of that laptop, 4 GHz).
Apologies if that was hard to follow!
I think it's a bit steep...especially with only 2 Mb of RAM!!?? - (obvious typo) lol
I see down further it does say 2Gb but I wish some people would proof their listings first, it saves wasting time & 'being led up the garden path' eh.

It says it only has 2MB RAM, but below he says it has 2GB of RAM.
EDIT: You beat me to it fnphoto.
Ok lets get technical about it.If you think of GHz as cycles per second (for simplicity's sake let's use two 1 Hz CPUs and assume that the system can perform one operation per cycle) then the system as a whole would surely still accomplish two operations per second and therefore be equivalent to 2 Hz (or in the case of that laptop, 4 GHz).
IPC and frequency
The CPU performances can be evaluated with the number of instructions processed in one second, in other words the IPS. It is equal to :
ips = i/c x c/s
C corresponds to the number of processor cycles and IPC to the average number of instructions processed per cycles. The cycletime is the number of cycles per second, or in other words the clock frequency, called F.
IPS = IPC x F
