Are any of these used rigs worth buying?! HELP

[levi10607]

Laptop decided to - how we say, kick the bucket? - this morning. On a bit of a limited budget, but do have around $600 - $700 to spend on a new set up. I do know computer specs fairly well, but I haven't had to worry about a new one in a pretty long time.

Currently comparing a few used rigs on Craigslist / Kiijiji, would love some advice on which (if any) of these are worth my money. (I realize how vague some of these details are, all the information was copied directly from the ads)

I have a monitor, keyboard, mouse and all those peripherals.

Option 5 and 6 are the only ones worth buying.

Option 5 is the better purchase of the two.

 

[Tree_Hugger]

Agree with Azathoth, Choice 5 is a really good deal for only $600

Edit: To elaborate a little, Choice 5's GPU and CPU are better than 6's and it has an SSD for less money.

I would also go with choice 5. Well rounded rig for not a lot of money.

 

[levi10607]

Thanks guys! Replied as soon as I saw this.

Dying without any sort of gaming set up. :\

An experienced PC Builder would know the importance of having a quality power supply, yet only one advertised an exact model. I would definitely verify the power supply of any of these computers before purchase.

...and yes, I'd agree with the others that option 5 is the best.
