^^^ Intel does have performance over AMD, but I prefer AMD myself as I dont like to shell out so much cash for procs. However, I can actually see where Mianmars is coming from, you saved in some places so you can afford better things in others. His is def the better build.
Well, I'd like to stay with AMD for a few reasons. I've always had AMD, so there is some brand loyalty. Their upgrade paths are also better and their products cheaper. I wouldn't say I'm entirely bound to AMD but unless the difference is significant I'd rather stay with them.
My biggest concern would be that I've heard/read the 1156 socket is pretty much on it's last legs now.
I was once an AMD fan boy too but with the release of Intel core i3,5,7 they really have surpassed Amd. You can check Toms Hardware CPU charts to confirm my point. About the 1156 socket on its last legs, well if u can wait for about 5-6 weeks then it would be better as new 32nm CPU's are coming on their way, if wait is no option then core i5 is way to go.
Having looked at my budget again I can't really spend as much as I had initially planned to, so this is pretty much what I've come up with on a budget of £600 max. Once again anyone's opinions would be appreciated, thanks.
