opinions please...

If you have programs that take advantage of HT and 2MB more cache. If not, then the choice is clear.

If you like the epeen, get a 2600K or if you always have second thoughts about getting the second best, get 2600k still.

For value, it's no contest, hands down 2500K. They overclock the same, it's just a benefit of 30-50% more performance thanks to HT and maybe 10-15% more thanks to the cache in best case scenarios.

What do you plan on doing with the chip?

The 2600k is probably worth is if you will be doing very heavy multitasking or use anything that is heavily threaded. It will also be slightly faster overall because it has 33% more cache.

Depends on what you do.

Are you a gamer and only do light encoding and other multi-threaded tasks? If so grab the i5.

Are you a music/video junky and will be using mostly multi-threaded apps? If so grab the i7.


The cache may or may not offset the performance hit you'll receive in programs that don't respond well to HT.

If you're big on folding (which you seem to be) i7 all the way, you'll crush bigadv.

The cache may or may not offset the performance hit you'll receive in programs that don't respond well to HT.

The performance hit is much bigger from the lack of cache than from HT. HT can never shave off than a few percentage ~1%-3% when it has an adverse effect and it rarely occurs (hardly actually) and should be a non-concern. Besides you can always turn off HT but you can't increase cache. But it's up to each person if that is worth the extra $100. For me, I would definitely go for it.

If you feel that is worth $100 grab it, it's your money.


Also note the i5-2500k has lower clocks and lower turbo... so when you see it beating the higher clocked higher turbo'ed i7 in gaming benchmarks wonder to yourself how come.
