I'd remove that link if I was you
Haha, replaced it with an OC card. Always buy from OC but the alternate site has guaranteed next day.
If you plan to add a 2nd 4gb 770 yes. If you play to stick with one i wouldn't bother, you won't have the grunt required to saturate 2gb or more of vram.
I think if I was going to upgrade Id stick with one card, but if one card couldnt use the 4gb then theres not a lot of point really.
Think I may well just see how BF4 pans out in the next couple of weeks and try running on ultra with a few settings turned down and see how I get on.
How can I tell how much vRam the card is using at any one time?
