A lot, probably. My $200 3rd gen I3 laptop can just barely not handle it- frames drop to 50 sometimes at absolute lowest settings. Gets constant 70fps on Paladins though
There should be a few. Although, if you want a pretty decent gaming laptop, you’re going to have to spend over 500. But this also depends on what kind of games you play.
For Overwatch, any computer that has at least an i7 and 1050 should be good.
Used, refurbished about 700. Look for 2.4ghz and up, 6gb ram, nvidia 700m and higher. 960m is recommended if not 1080. Best to save money for 1k and over
