Which will be better for gaming? I think that i7 is probably best, it will cost me a bit more, but it has a 8mb cache and hyper-threading. However I don't really know a whole lot about these things. You advice will be much appreciated.

If gaming is your primary concern...then get the 2500k, pair it with a p67 mobo and OC to 4Ghz +.

Then take the money saved and get a better Graphics card.

What is the point of comparing an overclocked 2500k with a stock 2600k..!! Anyway, for gaming the i5 2500k is better value for money compared to the i7 2600k.. The reasons being that it can clock to similar heights like the 2600k and HT is useless in gaming.. The 2MB extra L3 cache on the 2600k does not brings any noteworthy difference..

i5-2500K is fine at stock speeds for gaming, too. It's easily OCd to 4GHz, just change the multiplier...no need to adjust anything for such a light OC (apart from making sure you have a good cooler).

I agree with the point made above...an i7 won't have an increase in performance for gaming. I'd only consider it if you use applications that would take advantage of the hyper-threading as well as for gaming.

Generally speaking, the i5 is better for gaming than the i7. The i7's default speed is 100MHz faster than the i5 and it has Hyper Threading (HT) capabilities. Based on a review from Anandtech sometime last year HT does not improve gaming performance based on several popular games. Some games had a 1% or 2% decrease in performance. Therefore, the extra $80 - $90 for an i7 2600k vs. an i5 2500k is better spent on a video card or you can simply save that money.

However, based I saw a link to a video which showed Resident Evil 5 having about a 10% performance increase with HT. But that is just one game.

The only reasons you should consider the 2600k over the 2500k:

A) Money is no object
B) You are big into 3D rendering
C) You are big into video editing

Well, there may be more... but gaming isn't one of them.

There are very few games that will take advantage of more than 3 threads, because the value of hyper-threading on the Intel® Core™ i7-2600K is very minimal. So difference between the Intel Core i5-2500K and the Intel Core i7-2600K comes down to 100MHz and about $100 in price. This is why most people who know would say that for gaming that you go with the Intel Core i5-2500K.

The question asked solely which is 'best' for gaming? Answer: 2600k

BUT:

Price/Performance:

paying an extra $100-$120 for 100 more MHz, and a .5% framerate increase (typically a fraction of a frame per second) seems ludicrous, making the 2500k, by far, the best VALUE....

for gaming; 2500k. HT is of no use for games!!!

True that!

Although *why* one would OC the 2500K and not the 2600k (which typically OCs just as well if not better) seems...odd.
