What is the best Ati graphics card for ~£150?

I'm building a new PC and was wondering what graphics card to get. I have around £150 and my spec so far is -



Intel i5 75

Asus P7P55D - Evo

4GB RAM - 1333 MHz

650W PSU

2x Seagate 250Gb 8Mb cache RAID 0|||Get 4870x2 with 2gb memory gddr5.it will cost u around £140.it supports dx10.1.if u want dx11 then get 5770.its not powerful as 4870x2 but still not a bad choice.|||You could get the Radeon Hd 5830 or even the GTX460.....



GTX 460---You can find some 768mb versions under 200.00usd....

You can find the Radeon 5830 at around 200.00usd and under........http://www.newegg.com/Product/ProductLis…



Personally I would go for the GTX460(I only use ATI cards) as its a very good card and runs cooler and uses less power than the 5830.....



If you don't like any of those cards then the 5770 would be a decent card to go with...You have the power supply though for a higher end card like the 2 I mention......

Scott|||SOUNDS LIKE A HOT COMPUTER!!! BUT, SINCE IT HAS AN INTEL CHIPSET, TRY INTEL'S IN-HOUSE DRIVERS AT INTEL.COM/SUPPORT DRIVER/DOWNLOADS. THEIR GRAPHICS ACCELERATORS WHEN PROPERLY DRIVEN ARE VERY HARD FOR ADD IN CARDS TO BEAT, IF NOT IMPOSSIBLE...|||i got 2 ati radeon 5770 and they're sweet id get one of them, keep in mind they take up 2 rear panels
