ISO new CPU - computer question

[Mamma2004]

Costco.com is advertising two "deals" and my only concern is that the reviews are so mixed. Our Dell is overloaded with photos and video so we need another computer - not a monitor, just the CPU - ASAP.

Any thoughts on these or OTHER DEALS, even at a B&M? Thanks so much - it's rather urgent since we have 5th birthday photos and video yet to upload and I'm afraid of losing anything!
