Very good seller. But i guess some computers are better then others. Had mine about 2 months. Computer stopped working. I could send back but my personal info on it so im not doing that. Imma toss it and search for a new one. Also u can only have 2 screens plugged in and could not modify for 4 screens. I have bought 4 new screens and can only use 2. Like i said it was a good price. All i do is trade stocks and i traded on day shut it down. Next day blank screens on all screens and screens work on my friends computer. So if you buy god speed. They fix all issues. Only thing is computers you cant just send back. My bank info and stock info. So its up in the closet till i get a new one then im drilling and setting it a flame so my info cant be used.
