I'm going to build a pc soon. i'm on a tight budget so i decided to go with Gigabyte GA 78lmt-usb3 as my motherboard. i've read all the specs and it doesn't say anything about windows 8/8.1 support. but it does say that it's windows 7 ready. i found out that i can still install windows 8.1 as long as i install windows 7 first then update the driver to support 8.1. but will it make my pc slower or faster?
