Pros: Runs everything I'm throwing at it with no issues. World of Warcraft runs at 60 fps with all settings at high besides shadows, which I turn down a couple notches. In a loaded Wintergrasp or in wide open areas (flying over Ice Crown zone), frames can go as low as 30fps... Dalaran is crazy as we all know, so I only get 15-20 fps there. All raid zones, even Ulduar and Naxx are at or around 45-50fps in 25-man. Call of Duty 4 runs everything maxed out with no frame rate issues in single or multi-player online. Both WoW and COD4 look great too. I've been watching the GPU's heat very closely as I've read that can be a concern with this card. The fan auto-adjusts speed depending on load, and I never go above an average at load temp of 51-53C. Once, after playing COD for 5 hours, it was at 60C. So I'm happy to report no real issues there.

Cons: I originally installed Catalyst with the drivers, but I was getting much lower fps in WoW initially. After reading the tech support forums for WoW, it sounds like WoW - among many other applications - doesn't like the Catalyst program. I went from 40fps max in WoW to 60fps in many areas just by uninstalling Catalyst and then re-installing the drivers without Catalyst. Also, hopefully ATI will improve their drivers as it does suffer some frame rate performance issues in those wide open areas I was talking about earlier (i.e., flying over Ice Crown). I've been told by people online with nvidia cards of the same gen as mine that they don't notice a big slow down like I do (from 60fps to 30fps) in that zone. I'm guessing this is driver related as this card has plenty of power to handle these challenges you would think...

Pros: Fallout 3. 1600X1200 resolution. *Everything* set to ultra-high detail 50-100 FPS, depending on environment :) I'm very impressed with its performance, and a little bewildered at people who report the drivers are buggy. I would, however, note that the drivers I installed were direct from Sapphire's website (I didn't even bother with the disc) and I suspect many people are downloading them from ATI's website. Yes, I'm speculating -- but I bet I'm right. ;)

Cons: It dropped $50 in the past week! :( But so be it -- I plan to get another one of these sexy beasts and Crossfire them!

Overall Review: AMD Phenom II X4 940 ASUS M3A78-T Sapphire Radeon HD 4870 2X2GB Kingston 800Mhz LG Blu-Ray/HD DVD player/DVD-RW Western Digital Green 1TB Antec 900 case Antec Signature 650W Bought all these parts at newegg 1 week ago, and I'm not regretting a single decision! I've put together Frankenstein computer before (1 used part from this system, 1 from that system . . . ) but had never had a big package full of NEW computer parts dropped off on my doorstep, and it was a very enjoyable experience -- the resulting system was just a bonus. :) Thanks newegg!

Pros: Card runs all games at max settings. Noticeable difference from previous card which was a GeForce 8800 GT.

Cons: 1st card died after 7 months of average use. Turned it on one day to 3 red diag lights. Went though Sapphire RMA process which was really easy, had a RMA number in about 4 hours. 2 weeks later, Sapphire had sent a brand new card to replace the one that died.

Overall Review: Hope new cards lasts longer than 7 months.

Pros: What can I say? It's a beast! 1680x1050, smooth as butter in GTAIV, UT3, Stalker, Bioshock, Mass Effect. The 1GB version has noticeable playability improvements in many games over the 512MB. Most review sites agree it's worth the price premium.

Cons: I don't consider it to be much of a con but the fan speed (with full driver install) varies widely depending upon the load. It ramps up to be very noticeable when gaming but it's not an unpleasant noise, just "fan air" whooshing noise. Good thing the Z5500 drowns it out :) This card gets quite hot and even at idle the heat pipes are sizzling to the touch. It only exhausts some hot air out and my case is noticeably warmer now. Make sure you have some good case airflow.

Overall Review: It's a big sucker, barely fit it my case. 500W Earthwatts power supply with dual 12V@22A is enough to push this card, Core 2 Q6850, 4GB, 2 hard drives and dvd with no problems. AMD/ATI recommends a 500W minimum so I was wondering about that but so far no issues.

Pros: Great card no complaints. I had 2 - 3870's in crossfire that bench marked 18,000. This card single has done 16,400 with 3DMark06. Cod4, Cod5 all settings on high, runs great.

Cons: none

Pros: I ordered two of these to replace a pair of HD3870 cards running in Crossfire. One of these gives slightly better performance than the 2 HD3870 cards. See Cons for why I can't say how 2 of these in Crossfire compares to the 2 HD3870 cards in Crossfire.

Cons: One card would only work at x1 in either slot in a X38 motherboard. The other card worked at x16 in either slot. Due to Newegg not doing cross ships on warranty replacements I had to wait for the bad card to be received by them before they could ship a replacement. Now the card is out of stock so they are issuing a refund instead of shipping me a new card.

Overall Review: I realized after it was too late that if I had requested a refund instead of a replacement I could have ordered another card while they were still in stock and would already have it. Now I don't even know when or if they will have them back in stock. Now I'm worried I may end up with an orphan that I can't match up for Crossfire. Having been a Newegg customer since 2002 that has been my only gripe.

Pros: Excellent performance, drivers need to be improved though.

Cons: None aside from drivers

Overall Review: Video card works great with World of Warcraft. I can set all setting to max video settings with no issues at 1680x1050.

Pros: great bang for the buck, a 1gb 4870 for under $200??? gimme two please lol, i only bought one though. no dumb design on the card. runs everything i have on max settings @ 1680x1050. got it oc'ed to 800/1000 with 50% fan speed. mid-40°c idle, high-60°c load.

Cons: you'll need to manually adjust the fan speed. auto setting is junk, it doesn't cool it enough even on stock clock settings. i set mine at 50%. it can get loud, it's the loudest fan in my case. it's pretty huge, but you should expect that with these kinda cards.

Overall Review: games: crysis, cod4:mw, wow, bioshock, left 4 dead, tf2, hf2, portal, fallout 3, mirror's edge build: e8400 oc'ed @ 4ghz, ac freezer 7 pro, asus p5q pro, sapphire 1gb 4870 oc'ed @ 800/1000, corsair 2x2gb ddr2-800 oc'ed @ 870mhz, cooler master 600w, seagate 7200rpm/500gb, vista x64
