5 out of 5 eggsAMD Dragon Platform Rocks!

Pros: i hope this review helps anyone that owns this or thinking about purchasing this. i have been building computers since the mid 90's. I have

overclocked and gamed (is that a word) on this computer for over a month now with total stability.

MSI 790FX-GD70 BIOS 1.3 / FSB 250 / North Bridge 2500Mhz (250*10) @ 1.275v / CPU 3.75Ghz (250 x 15) @ 1.4875 volts / HT 2000Mhz @8 Multiplier

AMD X3 720 Black Edition overclocked from 2.8Ghz to 3.75Ghz with the AMD oem heatsink/fan (250FSB * 15 multiplier with 1.4875 volts)! When my room

gets hot i bump the multiplier down to 14 (3.5Ghz). Yes, you read that correctly! The stock heatsink/fan never gets over 45*C

OCZ Platinum 4GB (2x2GB) DDR3 2000 Model OCZ3P20004GK / running at 1666Mhz (250 front side bus) 1:4 ratio @ 1.93 volts. Timings verified with

(CL) 6 / tRCD 6 / tRP 6 / tRAS16 / tRC 27. This motherboard will not post beyond 1666Mhz memory (at least with this memory). i sometimes clock

down to 1333 with C

Cons: the AMD AM3 platform doesn't gain much performance from increased memory clocks like Big Blue's i7 chipset. But, i purchased this mobo AND the cpu

for the same price as one of Big Blue's i7 cpu's! Plus, i don't have to buy pricey triple channel memory. My gaming frames per second are equal to

the i7 920 in everything but Farcry 2. Read the Anandtech X3 720 review.

Other Thoughts: SPECS CONTINUED:

two (crossfire) PowerColor 4890's overclocked to 1Ghz GPU / 1.2Ghz memory = pwnsauce :-) i'm going to buy a third card.

one Western Digital VelociRaptor for my C drive. i dont need raid because im not video editing on this computer.

LG Blu-ray/HD DVD-ROM Model GGC-H20L OEM for watching Fast Times at Ridgemont High and Dazed and Confused on HD-DVD.

Antec 900 with three COOLER MASTER R4-L2R-20CR-GP Red LED Case Fans (replaced the stock blue fans) in the front (all 3 hard drive bays) and one on

the side and back. i got the 3rd hard drive cage from my other Antec 900 so this computer has three fans in the front. the case looks red beast

this way! i'm running the LG DVD drive externally (e-sata).

ABS Tagan BZ Series BZ1300 1300W power supply. i'm going to replace the blue LED's in it with red LED's. So my AMD Dragon Platform is totally red!

i turned the blue LED's on the motherboard off with the BIOS option.

2 out of 5 eggsMeh. Go buy another brand.

Pros: Fast Card. That's undeniable. The fan's been vamped up on the 4890 from the 4870, runs respectably quiet up to 45%. It's vacuum cleaner at 100%, but the temperatures in a good case shouldn't go past ~68c at ~40% fan speed.

It's also supposed to overclock really well, because while the 4890 is essentially and oc'ed 4870, there have been some changes in the design and placement of capacitors I think, that allow it to see much higher clock speeds.

Cons: -Coil noise. I RMA'd the card for another one and it still exists. Guess it's just part of the card though.

Buying this for the overclock? Forget it. Go with a different brand. I've heard of people getting 970+ GPU overclocks with a 4890 at *stock voltage*. That's what sold me on purchasing one over a Vapor-X cooled 4870, except prepared to be disappointed on the overclocks if you're purchasing Powercolor. Even with a massive 1.4 soft-voltmod (which I'm not comfortable with), I can only push this thing from a 910/1080 overclock to a 960/1140 before plain ol' ATI tool starts giving me artifacts. Keeping it at 1.36v gives me a 940/1100 overclock. And this is an RMA'd card. The previous one couldn't even get to 890/1040 before artifacts popped up (stock voltage.)

Other Thoughts: Do yourself a favor and get a brand whose construction is more reliable, if you're wanting to overclock. If not... I guess you could *still* get a Powercolor card... I only got it because of the combo deal with some ddr2 ram, and boy do I regret that decision... Non-refundable for a non-overclockable card.

Manufacturer Response:

Unfortunately, overclocks are going to vary from card to card, this is inevitable. Simply stated, some will overclock better than others regardless of how much voltage is being pumped into them. As far as the coil noise goes, feel free to e-mail me directly and I'll be more than happy to assist you with the issue. If possible, reference the Newegg review.

5 out of 5 eggsRMA'd

Pros: Very fast card.

Cons: Loud fan chatter

Other Thoughts: The card itself performed as it should, but the fan noise was too much to bear. I RMA'd for the same card in hopes that I get a normal fan. I gave 5 eggs because of the performance of the card.

3 out of 5 eggsupdate to prior review

Pros: it plays games

Cons: ok, well after a few weeks this thing is artifacting all the time and getting bad performance.

Other Thoughts: going to RMA and beg for another brand, this seems to be a problem card sadly.

3 out of 5 eggsRecieved a semi-defective model

Pros: It's a 4890. All the benefits of a 4870 1GB boosted clock speeds and overclocking ability.

Cons: I'm going to RMA my card soon. I'm getting an irritating coil whine UNRELATED TO THE FAN and UNRELATED TO THE TEMPERATURES whenever the card is placed under load. (Tested at 20% fan and 48c, put it under 3d load and WAM, irritating whine). The whine itself is louder than the fan is at 35% (up to which the Card is pretty quiet. It gets annoying after about 45%, but if you're wearing headsets you can crank it up to 60-70% without being too annoyed. Except, everyone around you might be) and the whole point of running a card at lower speeds and lower fan speed ruined if this coil whine continues to drive up the decibel levels.

Also, I could only achieve an 890/1100 overclock with this card before ATI tool started showing artifacts. Anything reasonably beyond 910 GPU or 1150 memory would crash the video card under ATI artifact scanning. I was hoping to get much closer to 1Ghz for $240.

Hopefully it's just a defective model. Will modify after RMA.

Other Thoughts: Q9550 stock speeds, 4gb 5-5-5-18 DDR2 OCZ RAM, Power Color HD4890 at 890/1100 gave me a score of 14997 in 3dMark06. With an overclock on the q9550 and a new 4890 at hopefully 980/1150 maybe we can inch closer to 16000 or more. Easily runs games at 1280 * 1024, without a hitch at 1600*1200, but anything beyond that you increase the workload drastically. The 4890 will perform well, but don't expect any miracles out of GTA IV or Crysis. As long as you don't expect full AA and AF at higher resolutions, you'll be fine with this card... if you get a good card.

5 out of 5 eggsVERY GOOD

Pros: very powerful chip. overclocked to 980 core/1150 memory and can still go higher. all games are maxed out, Crysis with max settings @ 1080p runs smoothly. huge value for the price given the ease of high overclocking.

Cons: jet engine fan, but it gets the job done. highest recorded temp 52 degrees.

Other Thoughts: this is definitely better than the competition at this price for the overclocking.
