thanks for the advice reddevil, is the bundle from compusa not very good? i liked it cause it is SLI ready and i remember hearing that i could put two decent video cards in and it would work even better than one real expensive one. Everybody is being really helpful but i think you are misreading my question. I have found a lot of walkthroughs on how to put your computer together, but what do i do after i put it together and plug it in? Do cpu's come with operating systems preloaded on them? or do i need to buy an operating system disc? Basically i remember watching a guy build a friend a computer once and he built it in only like 30 minutes but then he spent a few hours trying to make it work (software-wise). Messing with blue screen and programming stuff. That's the part where i wouldnt have any clue what to do. thanks again for being so helpful
