my aging Radeon 4850 be begin to go bad , so I have to start look for a replacement . after a lot of research I settle on this Sapphire Radeon 6870 . the card offer about double the processing power of the old 4850 , and run significantly cooler as well . installation be quite simple , although you would better make sure you be case have room for a double-slot card require two six-pin power connector . it be not a huge card , but it be not small either , so check the spec and you available space before you buy . I have to move a hard drive out of the way to make room for the card , but otherwise it go in without a problem . Performance have be excellent . the more powerful architecture be able to handle the same 1920x1080 resolution the 4850 do , but now I can run full anti-aliasing and anisotropic filter with nary a stutter . the 6870 also run much cooler than the old reference 4850 , with idle temperature around 100 degree -lrb- f -rrb- -lrb- 40 c -rrb- and 160 degree -lrb- f -rrb- -lrb- 70 c -rrb- under load . fan noise level seem pretty quiet too . good performance and cool run make this a very good choice . plus the price be right , especially with the rebate promotion available . I also receive the Dirt 3 edition , and be able to download a free copy of the game with the purchase of the card , a nice bonus .
