Nothing has really changed to me and around the similar 30 percent premium for nVidia's flagship full core:
HD 6970 -- 369 dollars -- GTX 580 -- 499 dollars -- around 35 percent
HD 290 -- 399 dollars -- GTX 780ti -- 699 dollars -- around 75 percent
Nope.
14 pages later and you missed that no one on our forums recommends R9 290X; also your comparison is not valid. 580 was about 18-20% faster than HD6970, while GTX780Ti is only 8-9% faster than R9 290X. To get a delta closer to 18-20%, you must compare the 780Ti to R9 290 where it ends up 15-18% faster. Therefore, the comparison to R9 290X is again invalid for performance reasons if you are going to bring up 6970 vs. 580.
So, we have
$399 vs. $699. NV is charging more than double for each % increase in performance compared to 5870 vs. 480 (+18-20%) and 6970 vs. 580 (+18-20%) generations. Worse yet, forget %, you are looking at a straight up difference of $300, even worse than the differential between $299 HD4870 and $499 GTX280 when 280 was faster by 20%.
This is like a repeat of unlocked 6950 in CF vs. 580. Unlocked 6950s ~ HD6990 and that card demolishes a 580 in the majority of modern games. Fast forward 2-3 years and $800 R9 290s will lay waste to $700 GTX780Ti in the majority of next generation games. There are only 2 things saving 780Ti right now: (1) lack of after-market R9 290s (2) NV's loyal fans. HardOCP and other sites which tested SLI are stating the with PCIe CF the stuttering issues are much improved vs. HD7000 series. Thus, under no logical circumstances for PC gaming performance, based on the mathematical formula of expected return and knowing the percentage of games in which CF works in the last 5 years, it is possible to recommend a single 780ti over a pair of 290s with only $100 separating them. On top of that 780Ti has just 3GB of VRAM which means even if 1 game needs more than that in the next 3 years, the 290s are ready to go. When a $299 R9 280X has 3GB of VRAM, it seems like NV is again cutting corners on a $700 card. No excuses. It should have either been $599 or 6GB of VRAM for $699.
Justifying 780Ti's price relative to the Titan also doesn't make sense since the Titan was overpriced for PC gaming from day 1. Even relative to NV's own stack of MSI Lightning 780 for $515 and cards like Galaxy HOF 780, the 780Ti is still piss poor value. To exacerbate the situation, 1600P and multi-monitor gaming will make R9 290s look even better and 780Ti's advantage over MSI Lightning 780 shrink even more.
Buying 780Ti for bragging rights is an emotional decision, not a logical one There is nothing wrong with that of course but then people should stop trying to justify the price of the 780Ti with logic as that's simply a lost cause. It doesn't work. Just say you want the best card for feel good factor and that's the end of it. No argument against that
