From your own posts it's obvious you don't know what you're talking about:
You're agreeing that they're the same chip unless you don't know how to properly word a sentence.  Even if you were responding to the other post, he was referring to the GTX 560 Ti (which he said was 50% faster) in which case you were wrong in either case.
		
		
	 
I'm really sick of you continually failing to understand what I'm saying. I'm speaking in plain English -- back off. You have consistently shown that you lack the ability to decipher something that is simple to understand. Since you are incapable of understanding what I meant there, let it go. It has absolutely nothing to do with the discussion, and was a personal quip directed at Balla.
	
	
		
		
			I'm not going to back off this claim you have that the HD 7770 has newer features (and I originally noted usable features too).
		
		
	 
Is it some sort of requirement that features must be usable at the very instant of purchase? You would think that since I'm clearly using the DX11.1 comment to convey the point that it supports something that is added in the future,
Here's a list of features that are new to GCN:
-  Partially resident textures
-  Eyefinity 2.0 (HD3D Eyefinity + extras)
-  Discrete Digital Multi-Point Audio
-  DX11.1
-  Vastly improved compute performance over VLIW4
-  Video Codec Engine
-  Steady Video 2.0
-  PCI-E 3.0
- Better image quality
-  Improved tessellation
Are all of these useful? No -- just take a look at PCI-E 3.0. It's highly unlikely you'd be doing any workload that would saturate that kind of bandwidth. It's also not my job to determine whether or not they are useful -- it's subjective, and highly dependent on what the user is doing with their video card. That is for the end-user to decide -- I'm just pointing it out.
	
	
		
		
			Please elaborate how the HD 7770 having DX11.1 is a big deal.
		
		
	 
I already stated why I can't, but I did give reasoning as to why it
 might be. Traditionally, DX revisions 
have been a big deal. It's about future proofing. It might be something to consider, depending on how much an individual cares about DX 11.1 support -- that is all I am saying.
If you'd like to read about it, check here:

Still, there's not much out there about the numbers behind the changes, and there won't be until the launch of Win8 at the earliest.
	
	
		
		
			As long as we're on the topic of education, what's yours?  I'm guessing college freshman.
		
		
	 
Sophomore.
	
		
	
	
		
		
			Sure it's relative, but you can't argue  price difference /w use since performance differences are drastic. The  only question there is do you have/are getting a quality 400~ watt psu  or better to run your setup, if not you probably should go to dell.com  and order your PC through them anyways.
		
		
	 
Yes I can argue that. If someone's building a low power rig, the 470  isn't an option. Performance isn't everything to everybody. Individual  needs differ, and when strictly comparing the 470 and 7770, a power  consumption-conscious user is not going to go for the 470. You're trying  to argue for everybody -- I'm saying that you can't.
	
	
		
		
			Yep, 470 was never a great perf/watt card, just a good overall value and  a very strong price/perf card since Q3 2010 they've been sub $200  retail.
Yes I'm talking used vs retail, serial based warranty makes it yours and  insured for the remained of it's warrantied period. There is a huge  market for used cards, your personal bias is causing you to use words  like anybody when you aren't speaking for "anybody" but yourself.
After the success I've had in the used market and almost everyone  adopting the serial based warranty process I'd be hard pressed to  convince myself to ever purchase a new gpu again, unless it was some  killer Black Friday deal. It's like buying a new car, as soon as you  plug it in and turn it on it's value just dropped 20%.
		
		
	 
Er, you're telling my that I'm biased, but you're talking about your favorite subject -- the GTX 470?
By  bringing used cards into the conversation, you are opening up a huge  can of worms. I've not paid attention to this whole thread, but I do  believe it's been used-GPU free up until that post. Everyone here is  comparing new GPUs at retail prices -- used prices can vary quite a lot,  and it's difficult to make perf/$ arguments because of that.
I don't disagree that a $100 470 wouldn't be a compelling buy... it's just not a relevant topic in this conversation.
	
	
		
		
			Performance wise the 470 is comparable to the stock 6950 in several  titles, but the 470 overclocks considerably better. Would you argue  against a $100 6950 in favor of a 7770?
		
		
	 
Maybe? If the user was concerned about power consumption, wanted DX11.1 support... you can't speak for everybody.
