1 X Corsair Force GT 60GB SSD

PSU
Corsair AX 850

Any valuable input would be much appreciated
Would there be a significant difference in performance if i used an 2500/3820 instead of 3770? Also, im getting the 3770 instead of 3770k since i don't plan to oc it.

What's your budget? What site(s) do you plan on using for parts? Do you live near a microcenter?

No real budget, im more of comparing performance to price ratios... and yes, I live very near to a PC/IT place so thats where I usually get my parts
