I would go with the Intel setup but change the motherboard to an asus or a gigabyte board if possible. And which ever system you decide make sure you get the intel corsair H70 since it's 3 Euros cheaper lol.
You'll get what you pay for and the intel's are WAY out in front with performance and price right now.
whats wrong with the Asrock mobo suteck? i've had loads of ASUS boards in the past but the two recent ones i had were an X58 ROG and a P6T and both of them broke after 9 months. I've had two AsRock ones since then.
I have had a couple in the past and I only got l little over a years use from them. I heard the new boards when the 2nd generation intel chip boards came out were now "quality enthusiasts boards". So when I built one for a friend with the i5 2500K, 8 gigs of ram and so on I thought I'd try again with the good prices and all, but again, disappointment. There seems to be a problem with the boards not wanting to turn on. I thought maybe it was the Thermaltake Armor case so I looked up things on the internet and found, sadly, it turns out to be a problem with that particular asrock motherboard. So I bought an Asus board and replaced it and so far have not had any issues. You notice I didn't trash the asrock brand? Maybe I just have bad luck with them so I don't recommend them when asked and I will never use them again. That's my sob story and the reason behind my firm belief they're not to be used. Hope it helps.
And why have you had 2 asrock boards since then? Just new builds and upgrades or did you have problems with them? How long did you have each before you changed it out? Was it over a year, two? lol Just asking
