so i've got an 80 gb intel ssd in a 13" 2.53 mbp and want to install windows 7 via boot camp. what's the best way of going about this? how much should space should I use for the partition? I'm probably going to use it primarily for gaming (l4d, other steam games) and maybe office. I was thinking of adding in a 640gb 5400 rpm optibay drive, and then putting that into two partitions as well (hfs+ and ntfs), then making the windows ssd partition smaller, and putting windows progs on the 2ndary HD.
