I know that 6GB will generally perform better than the 3GB GPU, but cost wise...it's astronomical for me to pay an extra $100.00 to outfit my A10-7800 CPU/FM2+ MOBO with the 6GB GPU. Is it worth ...
@Nikkei_Simmer for gaming you need a 1080/1080 ti for 2k. Gaming in 4K, we are not there yet. I don't know about photo editing in 4K. You would need to ask @chesterbigbird. You might need more Vram for that.
