well i have a sapphire radeon x850xt 256mb DDR3 VC, abit an8-ultra, and amd 64 athlon 3700+ san diego, 500W psu. tried setting everything to HIGH/Maximum in F.E.A.R. but it does not run smooth and runs laggy. could it be that the card isnt that great for the game.......its a 300 dollar card......i would think it should be fine with all settings on high/maximum
