4 out of 5 eggs

Pros: Great card for the price. Stock cooler was inadequate for me so i replaced it with an Arctic Cooling Accelero S2, and copper heatinks on all the ram and and threw on a 120mm fan with AS 5. Now idles at around 39*C and loads at 45*C with a mild overclock.

Can be run without a fan. Idles around 48*C and will overheat using ATI Tool to load the card (must use a fan, still, i can run my 120mm fan at 1000rpms and still keep it under 60*C)

Cons: None so far. Stock cooler is kind of noisy, but to be expected.

2 out of 5 eggsNot pleased

Pros: An inexpensive card. When functional, can handle quite a few games. I was play Crysis on High at 1920x1200 at a respectable 22-25 fps with this card.

Cons: Heat, heat, heat. Without manually forcing on the fan, this card idles at ~80 C. After playing for about two hours this card peaked at 96 C, over 200 F. It's been about five months since I got this card and I am now getting tons of artifacts in game.

2 out of 5 eggsNot satisfied

Pros: Powerful card that can handle quite a bit. Nice decal on the bottom.

Cons: As one other reviewer mentioned, I'm also getting the ATIKMDAG.SYS error about twice a day. Microsoft has a support page addressing this and says it's incompatibility with my motherboard (one of the new P43 chipset Biostars) and Vista. I'm not really sure why the error would be ATI related then. In all honesty, I'm not sure where the problem lies (and nobody else seems to know either) but it COULD be with this video card. I would go with another brand or a different ATI model just to be sure because you really do not want to have to put up with this error. Trust me.

Other Thoughts: Google the YouTube 4850 fan fix to create an ATI Overdrive profile and get your temperatures down, because they will be extraordinarily high if you don't. It's a simple process and takes little time however and is universally required for all 4850/4870 models.

2 out of 5 eggsNot liking this card =(

Pros: Nothing really *good* to say...Games look alright, but the cons outwiegh the pros by far.

Cons: I am recieving ATIKMDAG errors almost every 10 mins while playing games like EVE and Crysis. Ive researched this bug extensively and it seems that this started about 6 months ago and ATI has done nil about it. I would highly recomend doing research on this before buying an ATI card and find out if its been fixed yet before purchasing one.

Im RMAing this card and trying out a 9800.

Other Thoughts: This card got REALLY hot. would get all the way up to 90C and I had to go in and manually set the fan speed to get it to run and cool the card down.

5 out of 5 eggsGreat.

Pros: Good card, and Im running on PCI-Express 1.1 not 2.0. Improved framerate in most games, at higher detail. Makes COD4 look great as i was able to turn on AA. All around awesome value.

Cons: Heat. This isnt a major deal because the hotfix does help, and you can manually adjust the fan speed up. At 50-60% I see the best cooling vs noise ratio in my small cramped case. I wish I could have the fan kick in a bit more when the temperature went beyond a preset limit. At 100% fan speed this card is WAY to LOUD.

Other Thoughts: Before adjusting the fanspeed I was idling @ 80C when I had the case open. At 60% I see temps between 50-60C, after several hours of gaming before my OC. I currently have the card softclocked to 690mhz Core, and 1175mhz but havent tested the temps - I will likely run at stock anyway. Replaced a 8600gt SLI setup. Oddly the 8600 gave me a better frame rate in some older games, but 100+ fps constant is fine with me no matter what.

5 out of 5 eggsBright-O Makes old bodies new!

Pros: Great performance
Great price

Cons: None after fan fix

Other Thoughts: This baby runs hot, but after applying the "hotfix" I have not seen it go above 60C with load.

Brought my box from a 3dmark06 2242 (x850XT AGP) to 8893. I replaced my AGP card in my ASROCK 775Dual-Vsta with this PCIe card and it runs GREAT. This card is not on ASROCKs compatibility list for this motherboard but it works great (PCIe downstream pipeline disabled in the bios). All games run at highest settings except Crysis. JOY!

I am also, I should note, running this in a PCIe x4 slot. Intel C2D E6400.

5 out of 5 eggsWorth Every Penny

Pros: Cheap and fast, tops in the BANG/BUCK category, reasonable power draw, OCs easily, Oustanding driver support.

Cons: It runs warm, which would not be so bad if it vented outside the case. I got the idle down to 55 by adjusting the fan with a bios flash.

Other Thoughts: A pair of these puppy's on a x38 or x48 board SMOKES a $700 Nvida product

4 out of 5 eggsWOW! That's it, just WOW!

Pros: Fast and cheap! This replaced my X1900XT which still played most games well, but was getting out dated. Plays COD4, UT3, and Bioshock at 1650 x 1024 with max settings smooth as butter!
Overclocks pretty well once cooled properly, up to 700 core and 1160 memory.

Cons: Could not play Crysis at max settings (but came close). HEAT! Drivers?
Took a half an egg off for ATI and Powercolor releasing a product that idles at 75C!!! This of course being caused by the fan spinning at 20%.
Took off another half an egg for ATI and Powercolor releasing a product with buggy drivers. Only thing available is the drivers that came on the cd with the video card and the Hot Fix from ATI website. If you go to either Powercolors or ATI's website there are no drivers available to download yet for this card.
Took another half and egg for ATI and Powercolor releasing a product without sufficient drivers.

Other Thoughts: Replaced the very insufficient heat sink and fan with a Thermaltake CL-G0102 (Duorb) VGA Cooler which brought my idle down to 40C and 55C with load. I'm sure the stock heatsink would have worked okay once they fixed the fan speed bug, but in the mean time my video card would be frying and lowering it's life expectancy.
