Few questions before i upgrade my system again

[Palorim12]

these are my current specs:

Asus P8Z77-V PRO
Intel i7 2700k
16 gb ram
EVGA GeForce GTX 670 FTW
Thermaltake W0319RU TR2 RX 850w

Now what i want to do is upgrade to the i7 3770k because its ivybridge since the 2700k is sandybridge. I also want to buy another 670 and put it in SLI. My question is if I can do those two things with the motherboard I have and the wattage I have.

Any help would be awesome!

You could get the 3770k but IMHO the performance increase isnt worth the cost. I wouldn't trust that power supply to run dual 670's its a very low quality unit. In this list(http://www.eggxpert.com/forums/thread/323050.aspx) its a tier 5 unit and it's suggested to replace it asap.

OMG! Thank you for that link, I've been looking forever for it! I knew about the psu, but i lost that list you just gave me. I've been trying to get resell my thermaltake, but no bites for weeks. When i do get a new psu, how much wattage should i buy for the sli and everything else i have?
