So I'm looking at my desktop (rarely used) but I'm hoping to carve some time out to play fallout 4. Which brings me to my next dilemma I currently game with settings maxed on just about everything I play. But looking at system specs...



Here are the minimum Fallout 4 PC requirements:
* Windows 7/8/10 (64-bit OS required)
* Intel Core i5-2300 2.8 GHz/AMD Phenom II X4 945 3.0 GHz or equivalent
* 8 GB RAM
* 30 GB free HDD space
* NVIDIA GTX 550 Ti 2GB/AMD Radeon HD 7870 2GB or equivalent
Here are the recommended Fallout 4 PC specs:
* Windows 7/8/10 (64-bit OS required)
* Intel Core i7 4790 3.6 GHz/AMD FX-9590 4.7 GHz or equivalent
* 8 GB RAM
* 30 GB free HDD space
* NVIDIA GTX 780 3GB/AMD Radeon R9 290X 4GB or equivalent


My 3rd gen i7 3370 is ok. 16 GB of ram is spot on. Hard drive is fine. Windows has been 64 bit for years. But my gpu is a Radeon 7850 2 GB. Not 7870. Now to the system it reads as 7800 series. So I'm hoping it plays. But. I'm in the market for a new gpu. And one that i'll take to my next PC. (Target date of late 2016- late 2017 possibly early 2018 after new CPUs have been released.) So I can rattle off specs for of when it's closer. But I do have a 750 watt power supply currently. I'm looking to spend MAX $300 preferable max is $250. Which leads me looking at a r9 280/290. Thoughts? Should I bite the bullet and just upgrade to 290? My only concern here is dx12 seems to favor and Radeon, dx11 nvidia. Also and Radeon seem to use more power, which this is used sometimes for days without touching it so it may pay off to go nvidia (which I haven't in years so I don't know what to look for/equivalent other than looking at benchmarks.

Any suggestions?
