Ok, Thanks for the info guys! I will need a day or so to think over the info and try to come to a "rational" decision. I'll let you know what it is! I have to research and figure out how much I can get for selling the old stuff to buy a Xeon or a i7-3770k.
It would however help me if I can get an answer to this question in my mind:
If going for a Xeon for my 3D and photoshop work, will that give me a worse gaming experience than if i stayed with the i5-3570k? or even an i7-3770K?
If Xeon can still run most games, then I would go for that.
