BleepingComputer.com: Purchase Template: Budget $500 w/ monitor

Hi I'm looking for an all in one deal that I will be able to connect my PS3 to the moniter and still get HD like 720p. I dont know much about computers so I'm hoping you guys can help.

My budget for the new computer is: around $500 or less

What are the primary uses for this computer (IE: mail, web browsing, programming, games, etc)? mainly music, youtube videos, and some games

What software do you intend on using on the computer? nothing to crazy, maybe ableton live

Do you play games? If so, what type of games? if i play it will be world of warcraft so maybe a graphics card that will be able to handle that at high settings

Do you tend to have a lot of programs running at the same time, or do you close every program when you are done using it? i have a lot at once

Do you store a lot of pictures or music on the computer?
yes a lot of music

Thank you please give advice and for the monitor I'm looking for maybe 18-22, and i think it needs a DVI so it can be HDMI - DVI I'm not very sure as I'm new with computers.

This is a good monitor for PS3: http://www.newegg.com/Product/Product.aspx...N82E16824236053
I have no idea what kind of computer for $350 could handle WoW on high, though.

well possible medium also would be fine.

Even that is going to be a stretch. The best thing I could tell you is to get the lenovo IdeaCentre H210 H3643 and add a Geforce 9400GT. Not only does that total well over $500, I'm not even sure that will work because I don't know what kind of PSU it has.

Edit: I found that it has a 280W power supply. Newegg's power supply calculator added everything in that computer (including an extra video card) to a recommended 284W. It should work, but I'm not going to guarantee anything.

I Used to play WoW on this computer. I have a 2.8 ghz single core, and a Nvidia Geforce FX 5200.... Ran WoW great, and thats a terrible graphics card, so I doubt you'll need anything fancy.
