actually you are wrong, the 280x is now about £50 more than the 7970 and they specs as far as i can tell after 3 days of comparing them both on various sites and reviews is that overall the 7970 wins but only just, some people keep jumping on the fact that for crysis 2 you get 10fps more, which i admit is a huge difference to be honest when considering a card for gaming, but its not like that for every game but alot of reviews tend to only use that game, look at the crossfire 7970 compared to the single 7970 on some games it doubles your fps having crossfire, others the single actually wins... some things arnt as clear cut as they should be, but that was just one example im sure you get my point
sorry here is that link for you guys . stay awesome ;)
Guys I would really appreciate it if we could sharpen things up because I have done many,MANY video tutorials and reviews and pc mags reading up of this R9 280X vs the 7970 and please guys its always come out as the R9 280X on top. I would most hate my Favorite GPU comparison site to have false information out there for those uneducated buyers who absolutely cant do without you guys. At current pricing the 280X is about $100 dollers cheaper that's about R1000 and it out performs the 7970 everywhere. I also noticed as I was comparing the HD 6990 vs the R9 280X it showed the 6990 being a lot stronger than the 280x ,where as when I compared the 7970 to the 6990 it showed the 7970 was indeed stronger. This couldn't be further from the truth if , indeed my sources are correct and the R9 280X is stronger than the 7970?? Doing something about this would be very appreciated as I have for Many months and years adored this website and wouldn't want people saying your information is false just for anyone wondering here is a link to a video comparison. thank you
