Including tax this is more or less $800. Is 620W enough? At the moment i am using a 19 inch monitor(1440x900). If i get a bigger monitor or a dual monitor setup in the future will i be okay with this build? What do you guys think?
+1 with a Hard Drive. Its much more important at the current moment when you purchase the PC, there is nothing stopping you from later purchasing the SSD. Hopefully the savings you make with switching from the SSD to the HDD, can help you get a better Graphics card. Its a good card, however there is space for improvement, and I would recommend a 7850/7870, in the case that you do get a higher resolution monitor, as the 7770 will be crippled somewhat, compared to a 7850.
Everything else seems solid, good case, good gaming CPU, very good PSU, very nice motherboard for the $$$, good RAM, and hopefully you will ditch the SSD for now, and get a HDD, and get a SSD later.
A 1 TB HDD should do you fine in my opinion, however if you need more its always available.
Wouldn't go for a HIS IceQ, there are much better 7850's in newegg for lower prices. HIS are annoying with RMAing, when someone else tried to RMA that I was helping, they said the card worked fine, and sent it back, even though it was clearly broken.
