Your build will work as is.
But, I might consider some things.
1. For gaming, the graphics card is more important than the graphics card.
I have no problem starting with a strong cpu up front since it is easier to upgrade a graphics card than a cpu.
2. 3570k and Z77 are older tech. Newer haswell cpu chips and z97 should cost no more and be more amenable to future upgrades.
3. If you buy a "K" suffix cpu, it is to allow overclocking. For that, the stock intel cooler is not good. I would plan on a cooler with a 120mm fan that will cool better and be quiet. look at cm hyper212.
4. On a budget, look for a cheaper case. Antec and NZXT should have something at half the price.
5. 8gb of ram is good. The vengeance brand does not bring any functional benefits. Can you can find a 8gb kit of 2 x 4gb low profile DDR3 1600 ram for less?
6. Love the 240gb SSD. I like Intel and Samsung best for reliability. All modern SSD's perform the same. Samsung evo is often on sale.
7. 240gb can hold the OS and a good number of games. I would defer on the hard drive if you are on a budget. It is trivial to add a hard drive later for bulk storage of videos or backups.
8. Next week, we should see the launch of intel devil's canyon cpu chips. Of interest to you might be the Pentium K anniversary edition. It is a dual core chip that is overclockable that will sell in the $80 price range.
Few games can make use of more than 2-3 cores so that might be a good starter option that would let you start with a stronger graphics card like a GTX750ti.
9. Corsair CX is an ok budget psu.
It is tier 3 on this list.

I would try to buy a tier2 unit in the 600w range. Seasonic is my favorite.
600w will give you the option to upgrade in the future to a graphics card as good as a GTX780ti.
10. Advice: Download and read the case and motherboard manuals. Cover to cover.
Buy a #3 magnetic tip Phillips head screwdriver for assembly.
