How much is a sensible price?
"It is accepted practice that in a Wanted Ad anyone with goods to offer states their asking price."
I quote moderator @IronGiant here as I have no desire for me to get involved in breaking accepted practice
But to help you do what moderator says you should be (!) a few seconds search gave me the last similar cpu sold (not attempted to sell) here with a mobo for £100 (search i7 4770 & b85n itx board)
I have no desire to pay dumb ebay prices or CEX selling prices but as no doubt some think they are valid comparisons (they used to be specifically prohibited for comparisons here but cannot see that in current rules) CEX will give £96 credit for 4790k or £60 for 4770k
So, if you can let me know your asking price I can decide if I want to pay it
Hi got 4790k (delided with liquid metal applied) + asus maximus VII ranger + 16gb ddr3 2666mhz c11. Is no cooler but if you need I can add a stock intel cooler.
