I am looking to get a gtx 970 4gb in the next few days. I have heard that this card has a problem with vram. Like when the memory usage hits past 3.5 gb, it starts to slow down or something... I was wondering if certain gtx 970 manufacturers have this problem, or all manufactures of this card have that memory problem. I read somewhere that it is a problem on the hardware of the card and can't be fixed..? Anyways, on newegg they list several different versions of the gtx 970, and I am looking to go with this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814487088
