Best CPU for multiple instance od same application

[ankit.nagpal]

I want to buy AMD FX-4300 because it runs better in multi-threading: http://www.cpu-world.com/Compare/302/AMD_FX-Series_FX-4300_vs_Intel_Core_i3_i3-540.html

I usually run multiple instance of same application in my PC. For example, muliple windows of internet explorer, photoshop, visual studio etc. are open at the same time and run at the same time. Is it multi-threading? Is more core better in this case? A CPU that is better in multi-threading but worse in single threading environment, will work better in this case? Or processor with more number of cores but at lower Ghz than lesser core CPU is better in this case? What things should I keep in mind while buying a CPU for such kind of usage?

Very broadly, yes. Each instance would be its own thread, which means it can reside on whatever CPU core it would like (or rather what the OS puts it on).

It really depends. Generally for what you're doing more cores would be better, assuming you have enough threads/application instances to occupy them. But it's also a matter of load; IE isn't very CPU intensive, for example. So it may be that only one or two of your threads are eating much CPU time, in which case a faster processor with fewer cores would get the job done sooner.

Your scenario seems like it's not really using much CPU at all, so it wouldn't matter from your perspective.

Instead, I think your usage would benefit from more ram. So if you only have 2 GB, upgrade to 4 GB, because that takes memory to open multiple instances of many programs at the same time while still wanting to quickly switch between them.

Threads is what is good...

This. Chances are that you'll only be working on one application at any given moment, so the CPU won't always be pushed. I have 14 applications open on my taskbar, 20 tabs open in Chrome, 114 total processes running... and 10% CPU usage. However, I'm using 4.6GB of RAM.
