I'm building a gaming pc and was looking to use this video card Asus GeForce GTX 970 4GB STRIX but its out of stock is there any difference between that one and these: EVGA GeForce GTX 970 SSC ACX 2.0 4GB Graphics Cards 04G-P4-2975-KR and EVGA GTX 970 ACX 1.0 4GB GDDR5 256bit, DVI-I, DVI-D, HDMI, DP SLI Ready Graphics Card 04G-P4-0972-KR. Is it the same card made by different companies or different cards all together also is there any other cards with the same power and is around the same price range?
