here are the two cards... thats in Spain and you would not understand.... just look at the clocks...
hd 4890: http://www.pixmania.com/es/es/3493810/art/sapphire-tech...

HD 5770 vapor-x: http://www.pixmania.com/es/es/4209906/art/sapphire-tech...

my question: Could the vapor-x, by overclocking it, beat the hd 4890 at power?? DX11 is not questionable....
thanks...

do you mean raw performance or power usage? by any means i don't think that an overclock 5770 will ever beat 4890 in term of performance.

The 5770 with an ~950mhz OC should beat an 4890, but the 4890 OCs great also.
What is your case/PSU, and is power/heat important?



im buying a Nox Urano 600w power supply..... yeah there could be some problems.... the high noise level are killing me... so what should i do?

for 1280*1024 there is no need for 1GB, unless you plan to upgrade a 1080P monitor, 512MB save you money and perform identically.

ANd dont get the Urano 600W, low quality and only about 50W better than the enermax.


what?? inst good the nox urano?? .... ok ill see another options.... thank you so much!!! eres el mejor.... haha!!

No , the 4890 was the flagship gpu for ATI last generation.

A o/c 5830 can match/beat the performance of a 4890.

It's obvious that the 4890 is faster in terms of "raw" performance, the 5770 is basically the same as a GTX 260 give or take..

it depends on you. in dx9/10 games the 5770 will perform on par with 4870 or GTX260. in dx11 the performance will be cut down more since dx11 demand more GPU power
