@ RussianSensation: AMD is providing the same performance and featureset (R9 280X vs. 7970 OC edition) or worse performance and featureset (R9 270X vs. 7950 OC), all at a higher price and with zero game bundle included. .
Both NV and AMD release new cards that are often slightly more expensive then prices on clearance inventory for old gen products. HD6850/6870 vs. 5850/5870 is a prime example of that.
R9 270X is worse than 7950. Not denying that. I would never recommend R9 270X at $199 when HD7950 is $199-220.
On R9 280X, the situation is not as clear cut.
1) better after-market coolers
2) higher GPU clocks on some models without a large price premium
3) UEFI bios on some models
4)
TPU says the Never Settle bundle
is included
My honest opinion? The reason R9 280X is not particularly better than 7970Ghz is because of NV's ridiculous pricing. If 770 was $299-329 then AMD would have never been allowed to replace 7970Ghz with a $299 R9 280X.
Right now AMD has
no incentive at all to offer a lot more performance than 7970Ghz for $299 since 770 is $100-150 more expensive for 2-4GB versions. I blame NV's market positioning for R9 280X being nothing special.
Think about it:
MSI Gaming R9 280X 3GB = $310 without MIR
vs.
MSI Gaming GTX770 2GB =
$399
MSI Gaming GTX770 4GB =
$469 after $15 MIR
You say that 770 will perform better in games that take advantage of NV specific features such as PhysX in Batman but what about games where R9 280X will match or beat GTX770 for $100-150 less? What about Mantle for BF4? I don't think it's viable to justify such a large pricing premium on 770.
