The graphics card sucks (in that it barely meats the minimum requirements for something like League of Legends. I don't know what games you're looking to play), and logisys is the absolute worst
brand of power supplies you could possibly buy. I.e., every one I've worked with has completely shit out on me. That's why there's only a 1 year warranty on it.
Consider the following if you have the money:
This one's an absolute champ if you can drop $200 for it.
XFX Double D FX-787A-CDFC Radeon HD 7870 GHz Edition 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
This one's a good alternative if you can drop $110 on it.
XFX FX-777A-ZNJ4 Radeon HD 7770 GHz Edition 1GB 128-bit DDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
I choose XFX graphics cards because all of their cards come with a lifetime warranty as long as you register their serial numbers on the XFX website. It's wonderful.
As for power supplies:
I own this one (with a 5 year warranty) and it's been wonderful for over 2 years. And it's assuring to know that I have 3 more years for it to shit out and get a replacement for free.

EDIT: Your processor's decent. Just for reference though: It's on par with some older Core 2 Quads, and some of the first gen i3 and i5's. If you're looking to game, it's worth noting that Intel is taking the cake as far as having the better processors right now.
Also, you'll need a hard drive for your build.
And keep in mind that your motherboard only has a 1 year warranty as well and ASRock doesn't have the greatest track record with me.
Pretty much a big thing about the build is shopping for parts with the longest warranty time.
If you want to go deep, ASUS Sabertooth motherboards are awesome as hell and come with the longest warranty ever given on a motherboard (5 years). They cost about $200 though.
