I'm looking at 770's to replace the 260x I've currently got. Do you guys think that, with a 770, I'm going to notice a difference with a 4GB model over a 2GB model? I know the bus isn't the best (256-bit), but it might be nice in VRAM hungry games (like modded Skyrim) to have the extra headroom. What do you guys think?
I probably will. Isn't the word on the street that the 800 series will be like, 10-15% more powerful than the 700's, if that? I'm just trying to narrow down a particular model so I have a target to aim for.
The games that actually use more than 2-3GB of VRAM are few and far between, but when you come across one that does it definitely justifies the added expense. I had no stuttering on Watch Dogs, using a 4GB 670 and a 3770k, while there were people with beefier rigs that could hardly play it. I checked my VRAM usage, it was at 3.9GB.
Skyrim and Bioshock Infinite are two other games I've seen go above 2GB usage. Bioshock it was like 2.5GB, so not really anything major there. But for modded Skyrim, definitely try to get a 4GB card.
Plus, with the consoles using 8GB of unified RAM, there is a much higher chance of actually utilizing the 4GB of dedicated VRAM available once more multiplatform games come out.
