What card would you go with R9 or the Gtx 750
Go with the rig recommended in your thread at the bottom of that page but substitute that GPU from R9 270 to R9 270X for just a bit more $.
Let's review again why this makes the most sense:
$500 with 750Ti rig (where 750Ti costs $135) = baseline performance = 100%
$510 with R9 270 rig (where R9 270 costs
$145) => 24% more performance gives us a baseline of 124%
$530 with R9 270X rig (where R9 270X costs
$165) => 40% more performance gives us a baseline of 140%
GTX750Ti vs. R9 270 vs. R9 270X

You see for only $30 more on top of $500, you get 39% more GPU performance at 1080p
In other words, when considering the price/performance of the entire system, spend the extra $30 for a $165 R9 270X instead of buying a GTX750Ti 2GB for $135. And since you also get a choice of 2 free games with AMD, for someone like you there will be something to choose since you are just starting PC gaming. The R9 270X is a no brainer here.
Yeah the 750 to seems to run Arma 3 real well... No need to spend more on the 270 I guess
Not really. 750 would be a slideshow. 750Ti ~ GTX480/570 which nets you 28 fps average, with 22-23 fps minimums.
R9 270X = 7870 = 35 fps average with 28 fps minimums.
Neither card is particularly fast but R9 270X's minimums = 750Ti's average.
And are you only going to be playing Arma3 for the next 2 years? Again, in other titles, an R9 270X is on average 39% faster than GTX750Ti. If an extra $30 is such a deal breaker for you, what are you going to do in 2 years when you have to completely upgrade the GPU? PC gaming is not like console gaming where you buy a system with a $150 GPU and can game on it for 5-7 years.
FYI, R9 270X completely maxes out your CPU in Arma 3. If you intend to play this game for a long time (3+ years), save more money and get at least an i5-4430, or otherwise your next GPU upgrade will be bottlenecked by the FX-6300. This games is very CPU demanding too.
