i have a radeon x1950xt gfx card in my new phenom quad core pc (4 gig of ram) i am new to pc games and i have noticed that when playing games like crysis and counterstrike the gfx card temp ranges from 74 degree's to 86 degrees,should i be concerned about this? in a few week's i will have saved a hundred pound's to spend on gfx card and i was looking at the hd4850,would this be the best grfx card for gaming at this (£100) pound's price?or is there a better nvidia card for same price?thank you.
