you can hit the minimum specs by getting an i5-3570 and some GPU like GTX 980, GTX 1060 6GB or RX 580. That's around £140 in upgrade. You could opt for better GPU too to use in the future build.

I think Quest is more versatile choice in the long term as you can use it as standalone or PCVR if you upgrade your computer. PSVR probably has some sweet exclusives though.
