Hello,

Im planning a new pc and first i wanted the 3570K, cause of the 16x pci3.0, with z77 mobo.

But I saw that some say the 2500/k are better, because of the Hyper Treading. Performance with BF3 will be better then.

Next for gaming im using my pc for vectorworks (like autoCAD),

What will you suggest and is a 7850 (oc saphire) enough?

Thanks!
 
The 3570k and 2500k/2550k are both i5's which DON'T support Hyper Threading. I would opt to go for the 3570k since it's a little bit faster than the 25xxk's.

I can't comment for your vector works, but for gaming, a 7850 will do great. If you overclock, it'll do even better :)

As mocchan said, none of the chips you listed support HyperThreading.

Also, don't worry about PCIe 3.0. Despite what you'd expect, it will not make your video card run any faster, even if it's a PCIe 3.0 card. It will be literally years before even the high end cards need that much bandwidth.

As far as which chip to buy, I'd recommend getting the 2500k ONLY if you plan to overclock aggressively. It's much easier to deal with Sandy Bridge's heat output than it is Ivy Bridge, so they overclock much better. The average 2500k will do 5.0 GHz on air, while the 3570k will run into serious heat issues at around 4.4-4.6.

At stock performance, the Ivy Bridge chips will run faster and heat is a non-issue, so if you're going to run your system stock, get the 3570.

Thanks for the reactions,

I think it will be a 3570k,

So is hypertreading necessery? Or isnt it adding anything extra if I use the pc for bf3 / vectorworks?

Hyperthreading will provide a significant performance boost (25% or so) for the applications which can make good use of it. BF3 almost certainly doesn't, but I have no idea about vectorworks.

Thanks for the reactions! I cannot find any information about the hypertreading is useful for vectorworks. I saw that hypertreading is a poor version of dualcore's.

So it will be 3570K (10% faster than 2500 at stock speed),

Thanks and this lead can be closed!
