Hi. I have an older, Strix 2270e gaming m/b and am wondering what would be the best card to purchase for around $300 - give or take, for a gaming card upgrade? The first consideration is obviously compatibility (PCIe 3.0/2.0 x16). The 2nd are stability and performance. The 3rd is all the rest - power consumption/noise etc. If there is an option for, say, a little more $ with an immense upside in performance, please share that as well. Thanks for any help you can provide.
