Hm, while I don't know what everything on this computer is, I do know that 8 gb DDR3 is about the best RAM you can get, and 600 power wat supply isnt bad. After poking around, I learned that, on average, 600 watts is the minimum requirement to run your graphics card; I would consider upgrading your power supply to ensure your computer runs everything efficiently. Thermaltake is a good power supply brand.
1 TB is a lot of memory for a computer. As long as you don't CONSTANTLY keep downloading things, you will never have to worry about space on your computer. I5's in general tend to be decent computers, but I wonder if it's worth 1000 dollars; that is a queston for someone else.
Hope I helped!
