I need a new computer the one I am on now is from 2009. I have recently noticed a difference since my guild has switched to 25 man from 10 man. The only games i play are wow and diablo. I do not use my computer for anything else but wow. I live in the US. I do need a OS. I do not need any peripherals. I also have no idea how to build a computer. I do not really care about graphic settings, at the moment they are all on low. I just want to raid with better fps. thank you in advance for your help.
