How good of a computer is this? can you give me some info on what is does?

you will need to understand that if you get a computer that is under $375 then you won't be getting the full effect of a computer. The computer will come with basic memory speeds, which not even a 90 year old woman could deal with. All computers that are cheap come with 256 memory cards so you will need to upgrade that and that would be around 50 to 100 bucks. All computers do not come with Microsoft Office either so you will need to buy that which will cost you around $600.
