@Haldi:
Thanks for posting all these benchmarks and tips!
This kind of confirms what I've researched before. I was even thinking about Tri-Fire (maybe adding the third card after a while if it's necessary) before. But that would mean I'll either need a new (bigger) mainboard and case
or having a dual-GPU card that only takes up one slot...
This made me look into the rather new HD 7990 a little closer, since it sounds like it might be a real alternative. Obviously, frame rates are very good for this card, but what kept me from a decision was the fact that I've read quite a couple of reviews/comparisons who more or less stated that "it feels like a lot less FPS than it is". There are two different reasons I could imagine for this:
a) notorious Nvidia fanboys
b) strongly differing frame times, as this image suggests (as I understand it at least
):
The entire article (which made me rethink my decision) can be found here:
http://www.techspot.com/review/663-amd-radeon-hd-7990/page4.htmlA 7990 video I've watched on YouTube kinda confirmed this, but then again - it's YouTube, including sometimes bad compression and limited framerate, which might not be giving an accurate impression. Also, I suppose a game might feel choppy if you're not playing it yourself, not knowing how the player moved his mouse exactly.
It would be great to hear some opinions about this!
BTW (thought this info, which I had put in my profile would carry over to all my posts automatically, so sorry I didn't tell in my original posting): my CPU is an AMD Athlon X6 1100T running at 3,3 GHz stock speed. Might become a bottleneck soon, but that might be a topic of its own
@Mawrtin:
Thanks for that info^^ I was hoping to hear that
One guy even showed me a gameplay vid with a single 7970 GHz, which seemed quite a bit smoother (on higher settings) than my two 6950s!
What do you think about the new XT2 architecture based HD 7990? Would you have considered it if it had been released at the time you bought your cards? One thing that I also like about it is its relatively low TDP, compared to two single cards!
