Sorry to spoil you fun, but the reason they keep dropping their prices is because they aren't selling them as well as they would've liked.
The reality is nVidia keeps printing money despite (or maybe because) their so much battered rebranding.
I fail to see the reason why the current rebranding affects every forumist in such a distinct way they feel the need to share their pain over and over again.
If you ask me, all you're doing is increase visibility for nVidia products, giving them free publicity... and it is one of the reasons they are selling more then ATI does.
I have really bad experiences with ATI products, 3 video cards that give me artifacts on 2560x1600, in windows desktop, not even gaming, a 690g/SB600 motherboard that can't really handle AHCI/RAID modes without constantly locking up, drivers so unstable that they crash when I am looking at pictures slide shows...
They can drop their prices as much as they want. I won't be buying AMD/ATI for a time, they might do well in reviews, but living with them for a year or so is much more difficult then you might imagine. I had the chance to buy a 4870X2 at 30% OFF and I've chosen the much more expensive GTX295. The nVidia card just works, no problems whatsoever.
I've heard of 4870X2's artifacting their ass off (even in this forum)... it seems to be a recurring problem for them. They cannot handle dual-link DVI signaling properly. If you're going to call something "high-end" then make it work with other high-end components (like a 30 incher).
Sorry to be flaming out like this, but I've spent the last weekend reconstructing data out from destroyed RAID/JBOD arrays from my SB600... And from what I hear the SB700/750 have the same crappy PROMISE implementations of SATA in them. It's just not worth it, no matter how much less you'll pay for them.
I will stick to Intel and nVidia products for a while. Pay more, play more, sleep better.
