SandyBridge... 4.1Ghz w/HT vs 4.5Ghz+ in gaming!?

post #1 of 9
Thread Starter 
As above.
Recently picked up a Z68 board pretty cheap and have shifted my sigrig parts.
So im now looking for an SB chip, not buying retail as i dont like the prices, but i can get hold of an i5 2500k or an i7 2600 (non-k) for about the same price.

Which would be the better choice? The i7 is in fact slightly cheaper.

The i5 will obviously do 4.5Ghz + but do I really need more than the 4.1Ghz ill get out of the i7?

Opinions from owners and backup evidence please

=E= Will be running with my 6950 2GB, the chip will be under water.
PC is mainly used for gaming, eg... BF3

I would probably go for the 2500k. If the 2600 was a "k" I would go for that one, though.

I would go the 2500K. You can overclock it (fun), it is fast with gaming (fun) and it's all you really need. It will probably have better resale also since it's overclockable. 2500K.

Forgot to mention, the pricing is as follows >
The 2500k is about £18 cheaper than retail and the 2600 is £7.50 less then the 2500k.

=E= Decided on a new thread title.

Hard choice. Reason is these CPU's are insanely fast even at stock. And strictly speaking does not need to be overclocked. Even if we do it anyway.

So that 2600 will be very fast at 4.1GHz.

This is a hard choice since the 2600 is cheaper VS the 2500K. I don't know here...

3DMark11 with GTX580
2500K @ stock = 6281
2500K @ 4.0 = 6495
2500K @ 4.5 = 6597
2500K @ 4.8 = 6641
2500K @ 4.8, video card overclocked to 850 core = 6986

so, I got a bigger score jump from overclocking the vid card fairly moderately than I did overclocking my system from stock to 4.8. Now, that is NOT indicative of every game...but GPU rules the roost when it comes to gaming speed.

HT in its current states gives 2 things -

More responsiveness but a tiny tiny bit of less performance in tasks not utilizing all cores
More performance (anywhere between 3-15% depending on the programs optimization) but can completely kill the responsiveness of your computer in tasks utilizing all cores, however you can remove affinity from 1 thread in order to gain best from both worlds

Personally i find no ht a smoother ride all around right now but if intel fiddled with HT to automatically NOT dedicate all threads to 1 process it would be awesome
