Hey guys, I’m hoping you could help me out with a few things regarding upgrading my CPU. I will greatly appreciate any sort of help, but since I’m a novice when it comes to building a pc, I’d prefer getting help from people who really know what they are talking about. I basically have 3 questions.
1. I am thinking of buying a new CPU and since I have never built a pc before, I require some help with selecting the parts as I am not sure exactly what I need and what I don’t need. I have searched on the internet and so far and I am thinking of buying this upgrade package, which contains a CPU, a motherboard, and RAM. Here is the link. The site is in Danish, but it shouldn’t be too hard to figure out. CPU is an I7 3770K.

There are 2 things which I am not sure about regarding this. First of all, what kind of power supply would I need for this? My current pc has a 600w power supply (don’t know the brand) and I have no idea if this is enough for the intel core i7 3770k or not.
Also, what kind of cooling would I need for this CPU? As far as I can see, this package comes with a CPU cooler, which should be efficient enough on its own, but I am thinking of trying to overclock this CPU at some point, in which case the standard cooling won’t do. What kind of cooling would I need and how easy Is it to install this thing?
2.
My current pc has what I believe is a medium case. Would I need a bigger case if I decide to buy this CPU?
3.
This question isn’t as important as my other 2 questions, so if you don’t want to answer all 3, please just help me with my other questions. Anyway, I would like to know what kind of performance improvement I can expect from this CPU compared to my current phenom II, in terms of fps. Like, I’m going to be replaying Tales of Symphonia with LLE. With my current CPU, the game is playable with LLE, but I can’t go through most battles without fps drops. Would this be possible with this CPU? I’m also thinking about replaying Xenoblade with LLE. ATM, I can still get fps drops in xenoblade using hle if enough action is happening on the screen. Could I eliminate these drops completely with this CPU?
Sorry for the pretty long text but I want to include as much info as possible. I you need additional info just as me

thanks in advance guys.
