Aurora R7, RTX 3070 upgrade help (complete noob)
I am a complete noob when it comes to actual pc building and upgrading. I currently own an alienware Aurora r7 (460w, gtx 1080, i7 8700, 32gb ram) and having seen the new rtx 3070, I am starting to think through upgrading to it at some point in the next 12 months. I have gathered that I will probably need to upgrade my psu, so:
1) what wattage would be recommended?
2) will any psu fit/work with my pc?
3) will an rtx 3070 fit in the pc?
4) finally would the 3070 cause my pc to overheat I have seen lots of conflicting information and dont really understand any of it.
I really appreciate the help and any other advice you can give.
