Which is better value

Solution
Second build will game much better... switch to the board that is $70 cheaper... the board you picked is for over clocking and your CPU doesn't oc. First. Build has a top flight CPU, and a bottom run graphics card


Obviously you need enough ram to run games but 8gb has kind of been the standard/ minimum amount for gaming pcs for a while now so you shouldn't see any issues with 8gb ram. Although upgrading to 16gb is really cheap and easy to do if you need it.
 


Do you have a budget? If you're just looking to spend as little as possible just get a cheap 1080p 24 inch monitor and a keyboard/ mouse combo from a brand like coolermaster.
