AMD Radeon HD 7970 Video Card Review

Videocards/VGA Reviews by stefan @ 2012-07-31

Thanks to the new price reductions, the vanilla RADEON HD 7970 from AMD still remains attractive, can deliver quite good performances even at high resolutions as 2560x1440 and when overclocked it becomes a serious competitor even for the Nvidias' flagship, the GTX 680.

Comment from jmke @ 2013/01/08
I've just upgraded my Asus Radeon 6870 to the smaller brother of the card you reviewed, the Asus Radeon HD 7950; to be exact the: ASUS HD7950-DC2T-3GD5-V2

which comes with 900Mhz GPU (instead of stock 800Mhz) and features a 3 slot design for extremely silent cooling; does make a difference

but I meanly picked this card because of this

Full size DisplayPort Output, HDMI out and two DVI; that way I can keep my 3 monitor config without having to look into more adapters

reason for upgrade is because the HD6870 is getting a bit on the slow end at 5760*1200 resolution is recent games; Far Cry 3 was playable at low-med detail setting at ~30fps... with the 7950 that is bumped up to 40fps with high details
