Seems solid polepoop.
SSD wise, Samsung evo is the best performance/price atm.
Every other brand seems to suffer from failures way too often to consider them atm.
They are getting better, but I'd just recommend samsung until I see some positive longevity data on the others.
The gtx 780 should drop in price soon.
If my sources are right, they gtx 880 should be unveiled 19th of sept. (Released a couple weeks later)
EDIT:
If you plan on 2 GPUS in the future, stick with gtx 780.
If you don't, then the R9 290 (sapphire Tri-X) will save you some money and run just as fast in most cases.
