Thanks. Looks good, but alot of reviews say the fan noise is an issue. Things like that annoy me, to be honest. Is there a card that is comparable thats less noisy?
Also how does it compare to GeForce GTX 285, that seems to be popular, but is £232.
What is more important, shader clock speed or processor clock speed?
What amount of stream processing units should I look for?
Sorry for all the questions, I'm quite new to all this.
I dont think the fan would be very noticeable, only if you turn it up to high speeds.
The 4890 is about equal to the GTX 275, while the 5850 is a little better than the GTX 285. Both clock speeds are important but not ridiculously important. If you were to say overclock a 4890 by 75mhz your might only notice a 2-5fps difference.
As for stream processors, they differ between Manufacturers. Nvidia's processors work differently than Ati's so you cant compare them directly. With Ati the higher the better. The 4850/4870/4890 all have 800 stream processors. The new 5850's have 1440 i believe, and the 5870 has 1600.
Having said that I would still recommend the 4890 since the Nvidia equivalent is $100 more. The 5850 would be really nice but if its over your budget then thats fine.

Thanks for the reply.
Are ATI generally seen as better than Nvidia?
Is there a great deal of difference between these then? (all 4890)-
Ati inst necessarily seen as better, its a much better value though. Generally you can look to pay $50-$100 more for a Nvidia card over its Ati equivalent.
As for the 4890's, they're all pretty much the same except for their coolers and some might have a slight overclock over stock speeds. I would get the Sapphire with Vapor-X though because it has a very nice cooler and is factory overclocked.

Cool thanks. One last thing, will I notice a big difference between my current 9500GT and the HD4890?
