I'm not a cpu guy, but my i3s (just normal) report that they're 4 cpus at 3.4 ghz. I was considering upgrading my machine to i7s, cause they must be better right? But i've noticed i7s are also often 3.4ghz...

So... are my i3s decent then?
 
Your i3 is probably a dual core with hyperthreading. That's 2 CPUs (cores) in 1, where each core can do two things at once (hyperthreading). i5s and i7s are typically quad core or better. So an i7 would be able to do a lot more at once, put simply. There are also a lot of different technologies involved in the different versions of the processors, so it's not just numbers of cores or clock frequency (how many GHz).

However, the grunt of modern 3D games is handled by the graphics card and this is MUCH more important than which CPU you have. Spend your money on a better graphic card, if anything. And when it comes to the GFX card, don't concentrate on how much RAM it has, but rather which chip it uses (an Nvidia GTX770 with 2GB RAM is far better than a GTX750 with 4GB RAM).

While we're at it: SSDs have nothing to do with gameplay speeds.

HTH!

Edit: Run cpuz.exe (http://www.cpuid.com/softwares/cpu-z.html) to find out more about your CPU - there are lots of different generations of i processors with each generation being successively better/faster.

Trying to find a balance between the graphics card and processor. A too powerful graphics card will generate a "Limited CPU" and the graphics card will be underutilized. The most powerful graphics cards, currently, are certainly more comfortable with a core I7
 
The Alpha needs a quad core. Ok ! However, the alpha manages the hyperthreading ? Or it needs a true quad core ?

There is no TECHNICAL requirement for 4 cores. This is just a rule-of-thumb to enable you to more easily identify the kind of processor that will have the power to run the game.

For example a first generation quad core 2.4GHz i5, is probably capable of roughly the same performance as a latest generation (Haswell) dual core 3.4GHz i3.

Graphics cards don't require CPU resources, games do. It is however true that if you have a high-end GFX card and your CPU is incapable of meeting the computational demands of the game you want to play, you may as well not have that high-end card, because the game won't run optimally. Having a really good GFX card and a lower end CPU card, doesn't automatically lead to a "limited CPU".

Yet I read that the majority of the current games do not support hyperthreading. And I think Frontier has also indicated that ED does not support hyperthreading
 
If ED does not support hyperthreading, it leaves only two core, That will be enough ? Apparently not

Hyperthreaded cores appear to the operating system as independent CPUs. It's not something the game has to/can specifically support. And I'll say it again: it's not about the number of cores but the performance of the processor.

My little processor that could? :D
 
Most games from 2009 onwards support some level of multi-core use, usually they only exploit 2 cores but there are exceptions that utilise 3 or 4. The issue with writing software that exploit multiple cores is the degree of complexity of the code increases significantly for each additional core exploited. Tom's Hardware ran an article a while ago discussing this issue, the link is here

I have an old Intel core 2 quad Q6600 and it runs alpha perfectly fine at 2.4ghz, 4g RAM and a GTX660.

No need for spending silly money on super modern stuff for alpha, wait until you see reports from the beta test to see if the full game needs a modern cpu.
