Frequently Asked Questions

Is 8GB VRAM future-proof?

It's the current comfortable minimum for new titles — expect it to remain viable for 1080p gaming for a few more years, though the newest 1440p/4K titles are starting to want more.

Is 8GB enough for 1440p gaming?

For most titles at medium-to-high settings, yes. The most demanding recent releases with maxed-out textures may need a setting or two dropped.

Why not just get 12GB for the extra headroom?

If the price difference is small relative to your budget, 12GB is a safer long-term bet — but check the Value Score above, since a much cheaper 8GB card that performs better overall can still be the better deal today.
