Need help finding a decent desktop

[rblaesc]

hi.
ok, so unless I'm willing to wait another year or so, I'm stuck getting a pc from walmart (gift cards and such). I know they have the ibuy gaming ones. but I don't know if I really need a gaming computer. prefer under $500

so basically, I do the regular web surfing and I play games. right now, the desktop I'm using won't handle much at all. I want something that will let me play Sims 3 and WoW. those are probably the "biggest" games I'll be playing. so any suggestions would be greatly appreciated.

I know next to nothing about the computer itself, and building is not an option.

these are the ones I've been looking at?

but I'm open to suggestion thanks

The third option is the most powerful and could be the basis for a decent gaming computer with a graphics card upgrade . The current graphics card is quite limited

The second option is very weak graphically

The first option uses an amd processor with strong graphics built in . You could even add a relatively inexpensive AMD graphics card and the two graphics processors will work together .
