i7 2600k vs. i5 2500k

post #1 of 17
Thread Starter 
Hello! I'm new here, so please let me know if I do anything wrong.

I'm building a new gaming PC. It's primarily for Battlefield 3, but I will of course use it for many other games. On the BF3 Alpha forums, I had some people giving me tips for my CPU.

I was originally going to go with the i7, but I was informed that, for gaming, the i5 has near-identical performance for $100 less. Is this correct?

Thanks!
My Precious

The only thing the 2600K has over the 2500K is that it has Hyper-Threading. Most games only use 2 cores, so 8 Cores would have no benefit over no Hyper-Threading. If you are only using this rig for gaming, get the 2500K.

if this is a gaming rig you can save yourself the $$$ and go with the 2500K. It will oc to at least 4.5ghz and that will be more than enough to keep up with any game there is.

The LGA 1155 processors have an inherent limit of 16 PCIe lanes for graphics use (the same limit imposed on LGA 1156 processors), so if a gamer plans to use three or more graphics cards in CrossFire or SLI, we have to ask if Bloomfield/Gulftown and X58 offer the potential for more performance?

No! In theory, the current ultimate gaming platform (until Intel releases the LGA 2011 interface in the second half of this year) would be a P67 chipset paired with the NF200 bridge.

You won't need more than 4 cores within the future years (5 maybe?). Most games aren't optimized for the 4 cores and some still use only 2! So 2500k is the way to go

The i5 is fine for gaming.
The i7 has Hyper-Threading. Good for editing videos, folding, etc...

i5 is a nice CPU.
