Help! I have an ROG G20AJ gaming PC from Asus that comes with a GTX750, I just bought a Zotac GTX1070 FE and I'm not even sure if it'll fit, run, or have enough power to run in my rig. Would I need to buy an additional 230watt power supply for it to run? Assuming it fits and my motherboard can handle it(or bottleneck it)? Would upgrading the ram to 16gb also be a good idea?( and what type of ram would I need?) I called Asus and told me that opening my case would void my warranty so they didn't want to give me any advice. It would be very much appreciated on any help I could get with this. Here's a link to where I got the computer from, with more specifications if you need them. www.frys.com/product/8292376
