Okay guys i found a slightly used 7970 for around $300-320 . It seems to be a good deal, but i also noticed used 6990's selling for about 30-50 bucks more!!!


I don't know which one to go for! Im planning to watercool these cards and i really want the best performance possible. I just don't know if its worth to go with last generation 6990 for the price of a slightly slower new gen 7970....


Also you guys think it matters if its the sapphire 7970 version which is discontinued . Seems like sapphire replaced it with another card.

this is the discontinued 7970: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102961

they replaced it with this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008

i also read that there are people who are upgrading the bios on the 7950/7970 cards and getting a dramatic performance difference. Any thoughts on that?

Go with the 7970, the 6990 is a power hog in comparison I'd imagine.

i was in the exact situation. i found both for about the same price. i ended up going with the 7970. here is why. they 6990 is a 2gb card vs the 7970 being a 3gb card. in higher res, i play 5760x1080 the 7970 smokes the 6990. also with it being new tech the card is much more efficient and had more room to improve where amd isnt going to focus on bringing the 6xxx series scores up much were the 7970 could improve even more. also the fact that now the 7970 is consistently beating the 6990 in benches and game fps.

i really wanted the 6990 due to the baller status of the card hahah. ive always wanted to try a dual gpu card, but they are never better than 2 of the same series cards.

7970 or 7950. both cards when overclocked beat a HD 6990. for price perf you can't beat a HD 7950. at the same clocks the HD 7950 is 3 - 6% slower.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202006

the sapphire hd 7950 boost with model no 11196-16-20G uses a reference HD 7950 PCB. compatible with waterblocks from various manufacturers.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008

this sapphire HD 7970 is not a reference HD 7970 design. its layout is incompatible with waterblocks designed for reference HD 7970.
