Probably not, Couldn't justify upgrading from 6970 to a 79xx when performance gain would be marginal at best.
Custom water loop maybe?
You must be imagining it then as all the graphs suggest the 7870 is barely faster than an overclock 6970
I said 6950, not 6970 and i certainly did not say "overclocked 6970" which is a pointless argument anyway given that the 7870's overclock even higher than the 6970.
The fact is i moved from a 6950 to a 7870 and noticed a big improvement from stock, overclocked vs overclocked that gain is even bigger, it is and feels like a completely different card, its a vastly better card almost doubling the performance in some games.
You know; i could barley maintain 40+FPS on BF3 Ultra Preset, now i'm pushing 70 Avg...
If he gets a 7870 he will notice the difference, with a 7950 his world will be lit up like a christmas tree in comparison.
I presumed youd have been running the 6950 as a 6970 as most did but i new bf3 would be brought up well thats one game and special drivers to make it run fast for that one game 95% of the rest it's not much better tbh thus i dont consider it a worthy upgrade it would be like going from a 7850 to a 7870 an upgrade but not a very big one.He would be better off sourcing a second hand 6970 for xfire which is faster than a 7970 you have the board and the power supply to do it so that's what I would do if you can source a 6970 for around £100 ish.
I took delivery of a 7970 Windforce x3 Ghz today to replace my 6970 and have already submitted an RMA request to return under DSR. It's just not powerful enough for what I need (2560x1440). I know there's no single GPU card that will really cut it at that res on max settings but as a £370 upgrade I am hugely disappointed. I expect a 680 will be exactly the same underwhelming performance.
I expect I'm just going to keep my 6970 until the next gen come out and forsake gaming at 2560x1440. So as an upgrade for me, it's not worth it.
For 1080p then it might be worth upgrading, but not for higher res.
