First of all, alloud me to say hi, this is my first thread and this build will be my first build. I'm a Mac owner since almost three years, and i can't switch back anymore to any OS out there. But this build amazed me really a lot. And i subscribed to the forums just to say " WOW " to who built this. It blasted me so bad i wanna make this for my work. But since i don't use the machine for videoediting or renderings or whatevers, and i'm not so freaked out by having a so powerful videocard in my pc, there's some question i would to ask about to know if some changing would effect the setup that much. Sometime i play some game and photoshop some pic, my question is what if i switch to a Gigabyte 650? The price is good, and for what i need is enough.
