Ok, it is good the way it is but you could allocate money to different places better. Without changing anything, your power supply is shady at best. Get a good power supply, I cannot stress this enough! I went with a raidmax 850 AE. It seemed good at the time but now when I load up the 5V rail with hard drives and fans it became unstable. Get something from corsair, or coolermaster, or OCZ. Use the thermaltake power supply calculator to find your power usage and then get more then you need (100 to 200 watts more) so that you can account for capacitor aging, extra upgrades in the future and then overclocking. The graphics card is awesome (speaking from someone who is only running an HD6770) but for 30 bucks more you could get a HD7870 and it benchmarks so much more higher. As for the SSD and hard drive, I would scrap those and get the latest Seagate Momentus XT. It is a hybrid hard drive SSD with 8 GB of NAND flash memory and the hard drive moves the most used files (usually boot files and a few programs) to speed everything up. For only 130 bucks you can get a 750 GB drive and its 7200 RPM with a 32mb cache and the 8GB NAND. It is very high performing and the money you save will help put more money into the hard drive and graphics card. Just remember the Momentus XT is 2.5 inch so you need a case with a 2.5 inch hard drive slots so you need to buy 5 dollar bracket. This should save a good amount of money by buying that other hard drive. The motherboard is solid, the RAM is RAM it's a good brand, and if you buy the 3570K then you can just overclock the processor and the RAM will stay fine. The i5 3570K is amazing for overclocking because it runs very cool with low voltages to start. I really stress a cheap aftermarket heat sink like the hyper 212 or the hyper N520 because you can get to 4.0 Ghz with a cheap aftermarket heat sink. One other thing, a DVD drive is a DVD drive, go with lite on s the brand. It is cheap and they work as good as any other drive so you can save like 10 or 15 more bucks that way as well. I hope all of this information was helpful
If you plan to Crossfire, switch out the PSU I selected for a Corsair TX750V2 and upgrade the motherboard to an ASRock Extreme 4 Z77. The Motherboard+PSU I selected were strictly due to budget restraints.
