  I prefer the XFX.. but either way, any single one of those cards is outstanding...

  All this talk of tuning video cards for max flexibility and performance beings to mind a great idea. why not have a write up on all the neat things you can do with Riva Tuner.i only know how to do 2 things. setup overclocking and fan profiles but i know there is more neat stuff in there.
  
  and can you undervolt an nvidia card with software? how?

  Saphire and Powercolor have both announced a 1ghz GPU for the 4890, IF this is what got, i just thought you guys would have got higher since your seeing the max OC

  Gee that's funny, the GTX275 wins against the 4890 in every single benchmark nearly - or everyone one completely.

  Gee imagine that - I guess Derek wasn't red roostering the testing with a special manufacturer edition sent exclusively to him from ati - and a pathetic 703 core nvidia.

  Wow.
  It's amazing what passes HERE for "a performance comparison".

  Both are on the identical Core i7 system.

  Great article Derek
  
  Thanks a ton for the not small effort made to put this together.
  
  What I found very interesting, (besides the overclockability of the 4890) was just how close the 4890 is to the 285 in resolutions less than 30" monitor size. Close enough to be within the realm of "margin of error".
  
  This is all good to know as I have a 24" monitor I cannot see giving up for a few years yet:-)
  
  Thanks again. Oh, by the way....Those who can do...Those who cannot....criticize.

  -in every game ? when did this happen.

  Just 2 topics:
  
  1. How would the 4890 compare in price and performance to the 4870x2 or 4850x2. Would these cards give similar performance at a lower price?
  
  2. When is DX11 coming, how will it be implemented, and will it be any more efficient hardware wise than DX10? Even now, most games take a serious performance hit with DX10. Will DX11 require even better hardware?? If so I will either have to do a serious upgrade or run 2 generation old DX9. I have played Company of Heroes and World in Conflict, and I ran both is DX9 mode. The games looked fine and performance was so much better. DX10 to me has been a big disappointment in that it is so resource intensive without much visual improvement.

  I have to say, this is probably the most worked out OC article I've ever seen... and I've seen a lot of them.
  
  Now I understand OC-ing the 4890 to show what a terrific overclocker it is, but it's just not fair to do this if you don't OC the competition's GPU in the same price range (the GTX 275).
  
  Also, I failed to see you mention db ratings in the article. No one wants a goddamn leaf blower in their PC for usual gaming purposes.
  
  Again, I know it took a lot of time and effort to get this done, but I would have gladly waited to see a GTX 275 OC comparison.
