ive just brought the oculus rift and recently ive realised that none of my computers work for vr so i need the cheapest pc possible that can at least make the vr work (ive got a budget with a maximum of £400)an ideas?
That's a good start. Look at trying to get a 1060 or 70. A mobo that can take ddr4 and a good i5 or equivalent mate. You may get a good deal on a mobo and cpu from ebay ??
A PC with lots of gadgets inside and a thing to see in 3D that you put on your head.
Cheapest option is probably the budget computer from nearest consumer electronics store. They tend to come with bottlenecks, cheap components, questionable cooling solutions and preinstalled malware - but they are - cheap. Cheap at least to the point when customer wants to do upgrade and notices that standard GPU card won't fit to casing or that power supply had wiring for only 2 hard drives. Then couple weeks after warranty runs out, CPU fan bearings start seizing and gentle trail of smoke directs the customer back towards cheapest deal of the week.
Jokes aside... for rift cv1
gtx1050Ti with HDMI 1.3 video output (gtx1060 preferred), i5 (i7 preferred if possible), plenty of usb3 ports, 650W PSU (550W may be enough if it is high quality PSU), 16gb, win10, SSD+HD should do the trick.
