1 out of 5 eggsMaybe it could be ok

Pros: Received quickly. Card looked very clean.

Cons: Returned it quickly. DOA. Upon installing the card the fan went max. My computer would rival a 747 taking off at SFO (not really). Looked at ATI's monitor and temps were 90C at idle. I tried underclocking from 1000 to 500mhz and idles were still high. Tried playing starcraft II on low settings vsync on and temps hit 102C before dieing.

Other Thoughts: After going through Newegg's return process it's definitely not worth it for me risking to buy inexpensive refurbished items. Waste of time and unless you call it's a waste of money as well.

Manufacturer Response:

If you're still experiencing problems please inform our technician at or call us at (626)330-4700 ext. RMA Support (Monday-Friday 9:00AM - 6:00PM)

4 out of 5 eggsValue and Speed, Lacks Polish

Pros: 1.) Good performance.
2.) Fairly power efficient.
3.) Has 640 stream processors.
4.) Good quality construction.
5.) Uses GDDR5.
6.) Crossfire capable.
6.) Fairly quiet.

Cons: 1.) Blurry anti-aliasing in comparison to nVidia.
2.) Color and contrast levels not quite as good as nVidia.
3.) A little higher priced than it should be for its class.
4.) Slightly confusing driver release and download methods.
5.) Redundant and weird control center.

Other Thoughts: I purchased this unit to upgrade from an nVidia GeForce GT 640 with 2GB of GDDR3.

I was surprised at the performance increase. However, I was not pleased with the image quality of the Radeon. I predicted a difference in image quality, and the quality differences are mostly in the realms of the anti-aliasing clarity, color vibrancy, contrast levels, and overall polish of gaming graphics.

To summarize, the GT640 had much richer and more precise rendering, while the Radeon has much more power.

The Radeon delivers more performance per dollar, I believe.
