Computer parts don't get short of breath. Two GTX 670s use less than 400W together. 1kW PSUs are for crazy people that want to run four GTX 680s on an overclocked X79 build.
The 3770K will last just as long as the 3570K. Games do not use hyperthreading, and as long as gaming consoles don't support it, games won't either.
There were a lot of problems with the vertex 3 SSDs, get Intel, Samsung or crucial instead. If you must get a 200+GB one, get this one instead:
