New Computer Help

[mxer7734]

I have been wanting to buy a new computer for some time now but a lot of things have gotten in the way recently. I knew I could turn to OOT for some help so here I am. I am debating whether or not to get a Dell, an HP, one from my local computer shop, or any recommendations from everyone else reading this. I would like to get a "top of the line" one if that means anything. My current computer is from my local computer shop and have had it for about 2 years now and is great but has been very very slow lately. I have soooo many files, songs, favorites and lots of things are slowing it down and that is why im on my search for a new computer. Any help is very much appreciated. Thank you
