You can save maybe $10 by getting slower looser timed DDR3 but that wont affect the total budget too much. With that raidmax PSU i would bet that you would have to replace everything after attempting SLI with it. The PSU in the video is a raidmax 450 watt unit. http://www.corsair.com/cinema/movie.aspx?id=622747
Whats the total budget for the build? You may not be able to fit an i5 in.
kk well i just dropped 80$ on case another 60$ on lighting/HD just got a sata one. Um i would say about 600$ so i have about 450$ left. But little things like psu can wait. Cuz i dont need a new psu for my gpu since its pci. And ram and mobo and cpu are priority. There really isnt a budget. Since i just started to work. I will be making about 200$ a month about. So really upgrades on what i got like Psu arnt need atm.
Btw i have a 500w just pc psu.
