Crossfire/SLI isn't a "solution" as it's excessively expensive, extremely hot, extremely power hungry, and only works with certain games. Sure it's nice to have (sometimes), but 1080p isn't finished until single cards can max it.
I'm not to justify anything at all, I'm saying the fact is we can't do better now for a good long time on HD resolution, maybe on a higher spec display but on standard 1080p we are finally maxed. Do you people understand that? DO YOU PEOPLE UNDERSTAND THIS? I mean FINALLY we can max HD resolution, this has not been done, since besides the gtx 480 sli, well ever. When i realized it, I was literally shocked, it was such an awesome feeling.
I don't mind being outdated, since if the spec of the 78xx matches the 69xx and somehow AMD allows cross gen cfx, I can add a cheap and ultra efficient 78xx card, or buy a price dropped 69xx card. But yes you're right, it's inherently in there. I will always be sad that I'm an old geezer now, as everyone else has a new card.
I'm saying that no one needs to feel sad they're old now, because you can finally max HD. Before, ya no you couldn't. 200/4000 could look onwards in envy as the 4xx/5xxx actually got playable frame rates in the heavy hitting games, and double the past frame rates on most cards. and the 8xxx/3xxx series before them looking (I discount the 9xxx for nvidia) onwards to the 2xx/4xxx.
Though I'll give you that, sli/crossfire is a power hog and extremely hot, though with driver scaling at 90%+ and compatibility with all new generation games (with old gen never needing the prowess) I wouldn't call it excessively expensive (my old rig had a 460, before I ran a laptop, I still don't call it excessively expensive as all the games are supported and you get near twice the fps, so you get what you pay for)

Could you explain this please, or someone D: I'm not very good at understanding memory consumption

This compared to the 176 GB/s in Radeon HD 6790 with GDDR5 memory at 5500 MHz. All this power will be packed within an estimated power consumption of 190 watts
So it uses less energy while still increasing performance? That's pretty fantastic ! But what does bandwidth have to do with memory consumption ( I honestly do not know)
GAH I need a translated version lol http://www.rambus.com/assets/documents/091007_rds_sano_jp.pdf
pretty good explanation info from rambus: http://www.rambus.com/assets/documents/products/xdr2_memory_architecture.pdf

Differential signaling in combination with pin-efficient Flexlink C/A technology, enables XDR 2 memory to deliver a breakthrough level of performance with fewer controller and DRAM pins than single-ended GDDR5 memory. Any way you look at it, speed, power, bandwidth, robustness or pin-efficiency, XDR 2 memory is the best way to supercharge your next-generation graphics, gaming or multi-core computing design.
pretty big claims, hope they deliver.Edited by Spykerv - 11/16/11 at 11:47pm
