Mega Overclocked 4890 vs GTX280 ?

I'm thinking of buying a tweaked 4890 that's apparently good for 1100+ Mhz core and 1100+ Mhz RAM.

How do you think this would fare against the average overclocked GTX280 ?

Cheers,

Thats what... less than 10% performance increase on paper?

Most 200 series cards will happily overclock atleast 20-25% out the box without extra cooling.

Try to follow the context.

I'll edit my post to make it easier to see what i was replying to.

I have not seen any gtx200 series overclock 250mhz+ from the standard clocks. No where near it infact. Most i seen on here is greebo's gtx260 at 780 on the core. I think that card will do pretty nicely v a gtx280 overclocked if it clocks upto 1100mhz+ on the core.
 
All my 260 cards overclock from 576 (reference) to 729 fine on stock cooling and will go way beyond that with better cooling. Some of them even do 780 on stock.

The 285 is a bit harder to get those kinda % extra clocks on true.

and 850-980 is much bigger than 10% too, 850 + 85 = 935. Then any extra clock on top of that, I would say 20% clock is doable if %age of overclock is so important to you.

Good of you to use 2 completely different context too, use a 10% performance boost for the 4890, but use a clock speed boost for the GT200's to make it seem higher ;).

If I get the 4890 it will be used with a water block. If I tweak the voltage a little to try for say 1200Mhz on the core - 1200Mhz on the RAM (which it will do apparently) Would it maybe push the performance past the average GTX280 with the %15 overclock ?
 
Buy the 4890 card if you prefer ATI drivers, functionality, or because it is cheaper. Do not buy it thinking it will outperform an overclocked GTX280 - it will not.
