No. Not even close, I would think (I assume it's 2-way crossfire we're talking about? Not a 4-card setup?) I take it you already have a 3850 since you're considering getting another one in CF, right? Anyways, even a 4850 (dirt cheap) would offer significantly better performance than 3850s in CF. Unless you can get a 3850 for really cheap, I don't think it's be worth it - if you can get one for really cheap and you have a crossfire mobo, then it might be a viable upgrade option, but I'm for getting a new higher-end card.Im wondering if the SAPPHIRE Radeon HD 3850 512MB DDR3 was crossefired...
would this be more powerful and better performance than just one 4780???
Although I am really stuck on this Radeon HD 4870 512MB DDR5 card. Sounds great for the price!
