I'm still looking over what GPU I should be getting for my new rig and I think I've decided on the GTX 580. However, there are so many different versions of the GTX 580 I'm not sure which one to choose.
GTX 580 list
1) Is the 3072MB GPU useless unless I'm going to be using multiple monitors?
2) Are there any noticeable differences between the different GPU makes? i.e.
MSI GeForce GTX 580 Lightning 1536MB
Vs
Gigabyte GeForce GTX 580 OC Special Edition 1536MB
Lastly, I'm building this rig for the release of the major new games coming out Q4 2011 / Q1 2012 and having looked over some of the graphics on the new BF3 and Skyrim they look very demanding. I know the requirements haven't been released for these games and I could be way over shooting them but nonetheless it'd be nice to have a GPU that'd run stuff without problem. I've already ruled out GTX 590 and ATI 6990 simply because they're unnecessary overkill and way too expensive, but I was wondering how the 6970 matched up to the GTX 580?
Thanks
Rob
