Graphics Card on a budget?

Radeon HD 4890 would work well for your budget. Thats really not a "budget" card, its pretty high end.

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.

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