Just curious as to what the advantages are to having a 4gb vram graphics card as opposed to 2gb. In the future I may consider multi monitor gaming but for now I will just be Gaming on 1 monitor.
on 1 monitor; not much.
on a multi-monitor setup/really high res monitor; anywhere between slightly to marginally better performance than your standard 2GB card.
also, some mods makes large use of the vram, so if you're going to graphically mod games like Skyrim extensively, a larger vram is an advantage.
The advantage comes only over 1080p and running extremely large textures like Watch Dogs on Ultra. Aside from that, running at 1080p or less the gains are minimal.
In addition, card with larger amounts of memory usually have more memory chips. Sometimes they simply use both the front AND back of the board. More chips usually means a higher chance of one chip being the weakest link for overclocking of the memory. You can only go as fast as the slowest chip before you begin to see artifacts.
If you plan on 3 x 1080p monitors, grab as much VRAM as you can. But for a single screen, 2GB is still sufficient. More VRAM becomes more necessary when you have more pixels/texels to render, higher levels of Anti-alaising, and/or greater textures to render. Of course more VRAM also means you need a GPU with enough muscle to render frames with all that extra work load.
i have 4GB vram and 1 monitor so far. The only game i play is minecraft.
Do you plan to do anything in the future?
I plan on getting a second monitor (or using a old one i used before i bought my new one) so i can look at team speak for the server i play on. or for browsing and playing.
