Alright so i played the hell out of skyrim on the ps3 and now i have built my first pc as of right now all i have is a 7870 which i got for $100 but will be upgrading in a month or two . Im planning on modding skyrim to the moon, and i mean every graphics mod i can possibly squeeze in there but still keeping smooth gameplay, when i do and would rather get the 970 due to it power usage cause i only have a 500w psu what i want to know is a) can u exceed the 3.5 "full speed" vram with a ton of mods and b) if it can at that point will an r9 390 or a 970 even be powerful enough to keep the fps at 60 regardless of the vram if i pump that much eye candy in there i hope thats a clear enough question. Id appreciate real experiences with one of these cards and not just speculations i know u will rarely need more vram than the 970 offers at 1080p which ill be playing at by the way but i want the best experience i can get.
