prebuilts

Hi, I'm looking for recommendations for a good prebuilt PC, my budget is around £100-£150. I'm looking specifically at used ones but I don't know which one will fit my purposes. I'd like if it could handle light to medium gaming at 1080p which could be a big ask but I don't mind looking for...

Will the Visiontek RX 460 work properly in my HP Compaq 6300 Pro MT ? specs: i5 3470 8 gigs ram 300 watt psu it did not work on my dell PC so im just concerned.
