I am building a rig that needs to have lots of vram and have extremely powerful gpu ability for gaming at 2560 by 1440 with max eye candy etc. With a previously unprecedented number of high res mods for some of my favorite games I found out that I will reach very high numbers of vram usage. I wanted to sli the two best cards i could get for a reasonable price in exchange for the performance i would get. I basically am stuck between a 4gb gc edition galaxy gtx 670 http://www.newegg.com/Product/Product.aspx?Item=N82E16814162118, a 3gb 7970 vapor x ghz edition http://www.newegg.com/Product/Product.aspx?Item=N82E16814202001 and a 6gb 7970 vapor x ghz edition http://www.sapphiretech.com/presentation/product/?cid=1&gid=3&sgid=1157&lid=1&pid=1483&leg=0
I realize that 6gb is overkill even for my needs since i will be on one 1440p monitor, however I feel like 3gb would not be enough, especially to last 4 years into the future (the minimum this build will need to last me) as with enough hd textures some have reached near the 3gb vram usage in games like skyrim. I think that 4gb would be perfect, enough headroom but not wasted money. However, I have been hearing that the vapor x 7970 ghz edition is the absolute fastest single gpu card out there and if it would really give a huge performance difference vram aside (as i know the 6gb will not run out in the usable life span of this card) and it would considerably extend how long this build would last then it is worth the 1200 dollars to put them in crossfire.
Additionally, in many popular games like bf3 and skyrim nvidia had huge driver advantages and the gtx 670 would beat the ghz edition by about 20fps many times (according to the toms hardware review) which was amazing to me, but I have been told that is long fixed and the 7970 ghz edition is faster now by a lot.
Finally (I apologize for the long post) does amd have the equivalent of the nvidia inspector to add special effects like hq antialiasing or A.F. to games that normally would not have it in the game options menu? The software is important when buying a gpu as well.
