I want to buy a new card to run Tomb Raider, Far Cry 3, Bioshock Infinite, Assassin's Creed 3 maxed out @ 1080p 60Hz, and Crysis 3 as far as it will go. Would the Sapphire Dual-X 7950 Boost be enough for my needs? I would be willing to overclock a little, but only on stock voltage. My supplier doesn't have the other Sapphire 7950 versions, only the Vapor-X 7970 GHz edition as an alternative. I can get the 7970 for 133$ more, would it be worth it in terms of it being more silent or having significant added performance for those 133$?
