my hard drive exploded and i am blogging from an old laptop that works better than my desktop ever did
but its so little. quite honestly excellent for writing, and it's nice and portable too, but gaming is a challenge. luckily, i still have my old monitor, so it's still workable, but it's been awkward using two screens on my little baby desk. that said using two screens is also not something i've done many times before, so it's been quite fun to see all the things i can manage with a dual setup
anyways, i don't know what the move forward is. i'll probably buy a new computer soon, but the question always rests whether to build or buy. i guess building wouldn't be a terrible idea but i'm not the best with troubleshooting. but of course, buying is much more expensive. and absolbot hates expensive things
On a serious note, you should get your parts from Microcenter.
With all the money you will be saving you could probably be paying someone a small fee to give you helpful advice.
