I've just ordered a MSI 7970OC to replace my two HIS 6950s that have served me for over two years now. I've bought this card partly because I want something new to play with, it was also at a great price £275, and I get stutter in some games, not all, but some, namely Skyrim! Skyrim has become a game that I love playing and have found that I need to disable CF for the stuttering to go away which is annoying. Its been a while since I played BF3 and Crysis2 etc so I might give those games ago before my new card arrives so I have fresh memories to compare the performance too.
To be fair I feel a few people have talked smack in this thread, some claiming to never get any problems whatsoever imo is just BS and others who seem to claim that CF is just piss poor, the truth I feel lays in the middle, some games are ****e with CF and you need to work on it to make things better and yeah some games are just fine with CF, basically what I'm saying is if your going to go CF or SLi for that matter you have to expect a headache or two from time to time, getting all *****y with each other over it is a waste of time!
Post your experiences people help each other out and we can hopefully all have a better gaming experience for it, there's no need for pointless flaming its pathetic
So basically OP, if you haven't already, I'd go for single powerful card. I've had my experience with CF (always wanted dual cards, thought it looked sexy) but now I'm not into wanting to sort out a CF problem I want my gaming experience to be as easy and problem free as possible is all. Maybe one day I'll throw a 2nd 7970 in there or maybe a single 7970 will do me until the 9K series gets here who knows it all depends on when I'm bored and want a change again
