I'm building my first pc and can't decide which one
R9 290x tri-oc: http://www.newegg.com/global/uk/Product/Product.aspx?Item=N82E16814202079&cm_re=r9_290x-_-14-202-079-_-Product or http://www.newegg.com/global/uk/Product/Product.aspx?Item=N82E16814127787&cm_re=r9_290x-_-14-127-787-_-Product
or
gtx 970 g1 :http://www.newegg.com/global/uk/Product/Product.aspx?Item=N82E16814125684&cm_re=gtx_970_g1-_-14-125-684-_-Product
I would like to know which one is more future proof and will perform better in the furture and will be better in crossfire/sli and since if i get a 970 i will get the maximus v1 hero which has 3 way sli so would it be worth it in the future will it give me 2x the performance of a single 970 also eurogamer shows the 970 to be better: http://www.eurogamer.net/articles/digitalfoundry-2014-nvidia-geforce-gtx-970-review
my processor is the i5 4690k and the psu is the evga 750 watt 80 gold
