Do they really make a difference, being dual core with regular software?
No manufacturer ever said so.
Smash the Hourglass!
With The AMD Athlonâ¢ 64 X2 Dual-Core Processor
Frustrated by staring at the hourglass icon as soon as you try to work on more than three programs at once, especially when youâre working with digital media? Increase your performance by up to 80% with the AMD Athlonâ¢ 64 X2 dual core processor. Work or play with multiple programs without any stalling or waiting. Dual-core technology is like having two processors, and two working together is better and faster than one working alone. Do more in less time with the AMD Athlon 64 X2 dual-core processor.
Better Multi-Tasking Means Increased Office Productivity
Productivity in todayâs workplace requires smooth, efficient and seamless multi-tasking. The AMD Athlon 64 X2 Dual-Core processor delivers TRUE multi-tasking, allowing users to switch from one program to another without pausing for the computer to catch up and reducing annoying processing pauses. The end result is an increase in office productivity performance of 22% on average.
Most important is the fact that all this fuzz about speed is mostly due to commercial interests.
Intel and AMD prefer to sell topline CPU's because the price increases exponential while the performance doesn't.
The differences in performance with a good average PC sometimes can't even be mesure with a stopwatch.
On top of that for numbercrunching you don't need superpower.
Buying the fastest CPU has no correlation with the performance of the trader.
So if you buy a PC buy that CPU where the increase of the price matches with the increase of the performance of the CPU. Don't pay 50% more for a CPU that is 2% faster.
I run Tradestation, Esignal, Excel, Internet Explorer and my brokers software on a P4 2.4 GHZ with 512Mb of RAM without any problems.
I even have an old backup PC AMD K6 500Mhz that does the same job. Only at the startup he is slower.
It is like comparing a Ferrari 360 with a Porsche Carrera GT.
The Porsche is slighty faster but costs 3 times the price of the Ferrari.
A a good trader/investor you should keep an eye on the rate of return of your investment.
On the other hand, if you are succesful as a trader you can buy anything without bothering about the price.
depends on how "regular" the software really is.
the dual core processors are faster in most cases because there are many threads and processes running at the same time when a operating system is running
however, not many applications will directly take advantage of having a dual core processor, because they do not use threads, or do not use them effectively.
if you are running IB, you might able to see some difference, because Java Virtual Machine uses threads extensively.
if you are upgrading for performance, the difference of the new processor performance will be satisifactory
if you are upgrading just for the sake of having dual core. you might be disappointed.
tomshardware.com have alot of benchmarks regarding this topic...
but dual core does not mean it doubles the speed of the CPU.
I got a Pentium D, comparing with a Pentium 4 2.2 GHz I had before is really much more faster, I run a lot of programs at same time, no problems.

had to be costco member, request Wallet coupon book,
valid 2/20-2/25 only, apply coupon and instance $100 of at register to get the saving.
Do you have anymore specifics, links, phone numbers how I buy this computer?
What brand is it?
I am a costco member
Basically, if the application uses multiple processing threads to execute tasks in parallel, you will experience a significant performance boost, otherwise you will not be gaining much.
When I optimize systems using Amibroker for example (Amibroker doesnt use multiple threads during optimization), CPU usage of my dual-core machine stays around 50% - the one thread Amibroker uses consumes all the processor time of one of the cores while the second one is idle.
I hope that helps
