The Nvidia 3070 FE (4.4" x 9.5") will fit fine in an R7 and is compatible. If you have the 460w psu you will need to upgrade it first.   It really depends on what games you play and the use you put it (e.g. gpu vs cpu intensive) to see which component will bottleneck which.  For example you switch off hardware acceleration the cpu may be the bottleneck, turn it on and it may be the gpu. Or same deal gor example going from 1080 to 4k, that will put much more load on the gpu.  There's always going to be one component limited by the speed of another, that's just the nature of a pc.  I wouldn't worry about it too much with an 8th gen i7 and 3070.
Firstly hello to anyone and everyone reading this. I bought my pre-built gaming PC a lil while back (2018) and I'm looking to upgrade it now. Unfortunately I'm very limited with computer knowledge but can learn with a lil direction and a lot of advice if your willing to give it  . So please be patient with me, for I have learned a lot but still have far to go. I've recently watched a few YouTube videos on the process of upgrading and/or building and I'm planning to watch a lot more to wrap my head around it fully and hopefully avoid making expensive mistakes (if possible) Almost kind of like not building my own pc when I had the chance to  . I Probably would have avoided all these compatibility hazards and work-arounds ahead of me but based on the videos I've seen it seems to be inevitable regardless of what path I would have chosen. I really don't know cuz I've been very hesitant to open up my PC and risk damaging what's inside, and that's mainly because everything works just fine as it is but I am now frustrated playing on these low settings and even lower resolutions, while expectations of playing alongside my real life friends have been mounting with each passing AAA game that comes out and has multiplayer. I should also note that I bought a HTC Vive with my PC and if possible I'd like to open up my library to more VR games but only if the graphical quality is average or above and not below average as it currently stands. My guests love trying it out but they all say that its very fuzzy but very fun at least..  Anyways sorry about my life's story but hopefully you get a sense of what kind of person your helping/dealing with . Without further ado here is a summary of my PC below OS Name Microsoft Windows 10 HomeVersion 10.0.19041 Build 19041 System Manufacturer AlienwareSystem Model Alienware Aurora R7System Type x64-based PC Processor Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz, 3192 Mhz, 6 Core(s), 12 Logical Processor(s) BaseBoard Manufacturer AlienwareBaseBoard Product 0VDT73BaseBoard Version A00 Installed Physical Memory (RAM) 16.0 GBTotal Physical Memory 15.8 GBAvailable Physical Memory 7.91 GBTotal Virtual Memory 30.3 GBAvailable Virtual Memory 14.8 GB NVIDIA GeForce GTX 1050 TiIntel(R) PCIe Controller (x16) - 1901 Qualcomm QCA9377 802.11ac Wireless AdapterKiller E2500 Gigabit Ethernet Controller Sorry but I'm not sure what my power supply is like but if I remember correctly it was pretty low at the time of purchase.. the number 450 comes to mind but at this very moment I just don't know. Not until I open up my PC at least. I've already made peace that it's inevitable to buy a better one with hopefully a significantly stronger GPU and futureproof it because power is crucial at the end of the day. I still have to research the dangers of having too much power outside of the fact that it creates extra heat and a higher electric bill. I've also never overclocked my GPU or my CPU (if it is possible) but I'm now willing to take that risk and learn how to if it will save me more money to do so and not have to buy a newer part.  I was hoping to not have to upgrade for another two years but I don't know If I want to deal with these performance issues anymore. If you guys or gals can let me know what is holding me back and what is the best option to move forward then I would greatly appreciate your insight and advice. Currently I am lost with this motherboard and fearful of this compact mid-sized tower... Many thanks in advance!!!
