Intel Core i7 980 @ 3.79Ghz £stupid money 12.19
Intel Core 17 2600K @ 3.4Ghz £293 8.12
AMD X6 1090T @ 4.23Ghz (overclocked) £140 7.30
Yes its unfair to compare standard with overclocked but I don't care what's fair. I care about getting the best value for money in my next CPU purchase. So while I know I can overclock the 2600K brilliantly, it's still £293 and the motherboards are still expensive, and its lifespan is still limited with motherboard types changing so quickly on the Intel side.
you don't care what's fair? o rly? surely only a fair comparison allows you to determine which is the best value? the ONLY reason you would choose to compare an overclocked phenom II against a stock i7 is because you've already made up your mind which one you think is "better" and are trying to justify it to yourself.
since you're pretty new to the forums i'll apologise on the behalf of everyone here if it seems we are putting you down. your opinion is as valid as the next guys however, we are simply trying to avoid you basing your purchasing decisions on incorrect/incomparable data. in these forums the best prices to quote are ones directly from ocuk itself. they are usually the cheapest or near-cheapest trustworthy retailer on the net.
2600k - £234 passmark at stock = 9967
1090t - £130 passmark at stock = 6051
FX-6100 - £110-£140 passmark at stock = 6372

prices from ocuk. i had to guess the price for the FX as we don't know yet, so i just did a range.
so let's do a value calculation...
9967/234 = 42.6 for the 2600k
6051/130 = 45.5 for th 1090t
6372/140 & 6372/110 = between 45.5 % 57.9 for the FX-6100
as you can see even at the most expensive price it might be at (i would bet money it won't be more than £140) the FX-6100 is the same value at stock as the 1090t. bearing in mind it will overclock significantly better, it is hence quite a bit better value.
comparing the 1090t and the 2600k, you are correct in that the 1090t offers marginally better value at stock. however the 2600k overclocks significantly further, and absolutely destroys the 1090t in applications which use less than 6 threads. therefore imho the 2600k is in fact also better value than the 1090t.
taking motherboards into account, my conclusions still stand as the cheapest decent boards available for each chip are around the same price. maybe a bit cheaper for the 1090t but not enough to swing the balance.
hopefully you can follow my reasoning and see why people were criticising the way you had it in your OP. we're only trying to help you
