Looking to buy a desktop strictly for recording with reaper i plan on buying am amp which could be a 5150 iii or mesa recto..i am chosing to go with a desktop. No need for an amp if i am just playing at home and recording. Budget is $1,200 for everything. Suggestions? Also what small monitors and audio interface will get me the best sound quality with these amp sims? I am only recording instrumental guitar music.
