Gives you the first good reason. 100W difference load, 40W difference under idle.

Another good reason:

Note, the scaling on DX10 for the most modern of titles.

Another good reason: Anisotropic filtering

As I don't know the modeling software I can't pull up any benchmarks on that. In any case the performance from the 5850 is proportional to price and that performance will get used. You're always advocating for the present, what about the future? Its a much better card all around, just becuase DX11 games haven't started to really take advantage of the technology now doesn't mean that in 6 months time there won't be numerous examples of a distinction between the two cards. At this point the HD 4890 is at its peak and time will not be as friendly to it as a card which carries the latest technology and which still has room to grow.

 

 

Power consumption shouldn't be an issue unless you're sticking the card into a previously built box with an underpowered PSU. And no doubt the 5850 is a more powerful card than the 4890, but unless you're running at 1920x1200 or higher with high AA you probably don't need the former.

And "future-proofing" your PC - by that I mean, spending a ton of money on hardware that you don't need now so that it can be obsoleted in two years' time by a basic mid-range build - is stupid. Buying the price:performance "sweet spot" now and upgrading only when you need to will save you a ton of money in the long run with little performance loss. This is a trend that's held true since the early-mid '90s and the advent of the "graphics card race," and it won't be ending in the foreseeable future.

Noise? Even if you're not paying the power bill its still important.

The graph I showed you was running @ 1650 resolution. NOT 1920.

You're also assuming that the 48xx level is the sweet spot, why? The sweet spot of what exactly? In every case where there is strong scaling based on GPU performance the HD 5850 totally kills the HD 4890/70. I remember when the HD 4870 was the perfect solution for 2560 by 1600, then people said it was the perfect card for 1920 by 1080 then you're saying now that the card is the perfect product for 1650/1050. Things get obsoleted for a reason and technology moves on.

The HD 5850 is quite simply a better card than the 4890 for its features, performance, and noise levels. The only reasons why one ought to choose the former over the latter are shortsighted ones based on the present conditions in the market today.

Heres another one: Would you rather run at 30FPS or 45 and have a margin at 1650/1050 for AA if you want?

Or even the difference between good and average on Crysis?

And for a modern game which shows excellent GPU scaling, enter HD 5850 again at 1920 by 1080

So you tell me?

 

 



Tease.
