I think i does, but you may not notice. It has the say affect as the TV in the store. You can compare the screen quality at the store, but almost anything will look good on the wall at home. Somewhat the same with SSD's - you can look at all the charts in the world and compare specs, but sometimes it feel a bit like the same. Though I recommend it very much for some program, games etc. The Samsung 830 would be an excellent choice. As for the other components you could just change the mobo with the Asus p8z77 Pro and the graphics card with a non-reference one.
Anyways, the build I presented above shows excellent value, and you would get decent gaming performance out of the budget you have.
