I cant seem to find many charts that compare graphics cards this many generations apart. I want to know how crossfire 512mb 4850's stack up to a single 6950 2GB. Would there be a noticeable difference?
2 4870s performs very similarly to a 5870, which would put 2 4850s close to a 5850, which is slightly below a 6950, but since they are only 512MB 4850s they will take a slight hit due to less vram at high resolutions so a single 6950 would be better but not a ton.
Well I currently have the 4850's and was planning on spending my cash on crossfire 6850's but I recently purchased Cataclysm, and knowing that I will see at best 30% increased performance out of the CF I was thinking of getting a better single card now and buying a second one in 8-12 months. I am expecting the jump to be huge from the 4850s to the 6950 for WoW, but hoping the performance will stay about equal in Crysis.
