I can run skyrim on 1080p on 2 gigs. If you mod a lot, it will dip slightly. A little healthy overclocking will do ya some good as well. Is 3.5 supposed to be a cheap blow at the 970?

Is 3.5gb vram enough to play gta v modded and skyrim w/ mods and txt. packs at 60fps high settings?

Yes it is.  I'm also assuming that you're talking about a GTX 970.  If you haven't purchased the 970, I would go with a R9 390 instead.

Depends on the resolution you're playing at.

 

I can max out skyrim at 1080p with 80+ mods easily with my 970, FPS never goes below 40 or so, usually staying around 60+.

 

 

Also, the 970 has 4GB of VRAM, not 3.5GB. (Yes, I know the last .5GB tends to be slower, but that doesn't mean it isn't there.)

Specs: CPU - Intel i7 8700K @ 5GHz | GPU - Gigabyte GTX 970 G1 Gaming | Motherboard - ASUS Strix Z370-G WIFI AC | RAM - XPG Gammix DDR4-3000MHz 32GB (2x16GB) | Main Drive - Samsung 850 Evo 500GB M.2 | Other Drives - 7TB/3 Drives | CPU Cooler - Corsair H100i Pro | Case - Fractal Design Define C Mini TG | Power Supply - EVGA G3 850W

I'm so confused. I'm getting both answers. Is the r9 390 worth the trade off of performance in most cases but for heat and noise and less driver support.

Heat - the Nitro 390 is cooler than 90% of the 970s available today.

Noise - I doubt the 970 you're looking at will be quieter than this card - maybe if it's a KingPin or Classified but yeah. Sapphire are the best along with EVGA

Drivers - currently, believe it or not, AMD have slightly more stable drivers than Nvidia

VRAM - Once you hit the 3.5 wall - the 970 starts using the slow part causing all 4GB to run on a 32-bit bus in order to harmonize with the slow part - read @D2ultima 's guide on the subject.

It's not on a 32-bit bus. The 32-bit controller part that interfaces with the slow vRAM must essentially do the work of two 32-bit controllers, so it halves memory bandwidth for the rest of the card synchronizing with it.

 

So it acts like 7 x 16-bit controllers, not 7 x 32-bit controllers, for a 112-bit memory bus.

 

It's not exactly as bad as a single 32-bit controller (EVERYBODY would feel it at that point) but it is bad.

I have finally moved to a desktop. Also my guides are outdated as hell.
