I have an ASUS A7V8X-X Motherboard(Link) and I'm looking to get a new harddrive. Looks like to me I can only have a ATA/133 or ATA/100 harddrive. So I was looking around and I think these are the two best ones for the money/size/speed. What do ya'll think? Which one is better? Or maybe there is even a different one I haven't seen yet that ya'll suggest. First harddrive Second harddrive Also, is there a big difference or no difference at all between ATA/100 and ATA/133 harddrives? This will be a gaming computer primarly, so keep that in mind. Thanks for the help.
