The HD 7970 OC edition makes the R9 280X irrelevant, because one gets equal performance, same featureset, lower price, and game bundle included.
Never Settle game bundle is included with R9 280X. Some after-market versions of R9 280X have improved their coolers vs. the 7970Ghz.
The Asus DCUII TOP is a much improved cooler vs. the 7970 Asus DCU model. It is actually identical to the cooler used on the GTX780 Asus DCUII.
Sapphire has the new triple fan cooler
The Gigabyte Windforce is improved over the previous revision.
There is also the UEFI bios for some of these R9 280X cards which will allow them to boot faster into Windows.
For the games that favor NVIDIA's GPU architecture, the GTX 770 will be noticeably faster.
The same applies for games where GCN is faster, making your statement odd to say the least. This is why we look at average performance.
And right now one can get a Superclocked EVGA GTX 770 for $399 w/ MIR and with a free copy of Batman Arkham Origins, which is at least a much better deal than GTX 680 which had lower performance, higher price and no game bundle in comparison.
Even if you assign $50 value for that game, the 770 is $50 overpriced. No point in comparing 770 to 680 since 680 has long been discontinued. What matters is today's market situation.
This. 2 years and they are only introducing 2 new cards (290 and 290X which we havent seen yet) Pathetic. Should have been all GCN1.1 versions. Was thinking about selling my 7950 to move up, but since I can't get an actual upgrade, I guess my money will go elsewhere.
There are no viable upgrades from AMD or NV from 7950/7970/670/680 OC without going for R9 290 or 780.
For people who haven't upgraded, they can now get 7950 for $199-220, R9 280X/7970Ghz level for $299. When 7950 came out nearly 2 years ago, after-market versions like MSI TwinFrozr or PowerColor PCS+ were $469-489 USD!
I think it's more or less understood that for people with 7950-680 OC level cards, the next upgrade is either in 12 months once 780/R9 290X drop in price OR when 20nm cards arrive.
