Pros: Very fast, very cool, PhysX works and is noticable, drivers are excellent, screams and flies. EVGA warranty and support is better than any other in the business, period. After dealing with the nightmare of ATI Radeon, I plunked down tha cash for this card and could not be happer. Under load, temps are low 70 C, very manageable.....and this card's visual effects toast anything I ever saw with 2 3870s in Crossfire...the games' auto detect settings are higher, and quality is far surpassed.

Cons: None that I can see other than the price point.....but I spent over $1000 and 3 months plus endless hours of terrible support, non working "solutions" from support, and $$ shipping cards back to manufacturers in trying to get ATI 3870 solutions to work with no luck.

Overall Review: I have a crossfire mobo, and after going through 4 HIS Radeon 3870s that I could never get to work (phsyical mechanical failure....HIS is the worst company I've ever done business with), a Sapphire 3870x2 that had incessant problems (random freezes, noisy fan, artifacting, slow framerates), and an ASUS 3870 that would constantly crash and cause driver failure, I abandoned ATI and Crossfire and bought this card. I have literally spent the last 2 months trying every driver and hardware configuration known to man to get ATI Radeon 3870 to work on a platform that is designed for ATI crossfire, and I can't even get them work as single card solutions, let alone in Crossfire. So, I say "forget ATI' and buy one of these, and I literally just plug it in, download the drivers, and IT LITERALLY JUST FLAT OUT WORKS, RIGHT OUT OF THE BOX, PERIOD. NO DRIVER UPDATES AND RE-INSTALLS, NO MYTERIOUS CRASHES, NO DRIVER FAILURES, NO COMPATIBILITY ISSUES, NO OVERHEADTING PROBLEMS......IT JUST PLAIN WORK

Pros: Good engine and solid design. Excellent cooling system design.

Cons: THESE CARDS HAVE KNOWN ISSUES WITH THE FAN-SPEED REGULATOR. Bought 2 of these cards to run in Crossfire. Terrible issues with HIS drivers even after clean re-install. Main problem is that many of these cards' fans never cycle above 25% stock.Something in the BIOS is missing because driver changes do not fix.Card starts out booting up fine. But, as the card comes under load, the fan stays at 25% and the card's heat climbs. When the card gets too hot, it fails.Total VPU failure to black screen and then Mobo kicks in to re-boot. Many owners of these cards have reported this issue, and not just in HIS (ASUS and Sapphire also).

Overall Review: This problem CAN be adjusted with 3rd party software (Riva Tuner, etc.) However, if you've already overheated the card several times not knowing what's up, then the card may already be damaged. However, in using 3rd party software to change fan speed, you void warranty. 1 card is fried, and the other is okay if fan speed is at 100%. HIS customer support sucks, and getting an RMA is tedious. So, I spent almost $600 for 2 cards, neither of which have working fan speed regulators and 1 of which is fried and needs total replacement and the other that requires manual fan control with 3rd party software. Nice going, ATI and HIS. Ugh!

Pros: None.

Cons: COMPLETELY Dead after 2 months. When it was working, it had UNACCEPTABLY Slow Speeds due to a really lousy chip and sub-standard drives. Poor Documentation. In 80 page manual, about 10% of the information is actually functional, and most troubleshooting and other information are worthless. Worthless Software Interface. NO CUSTOMER SUPPORT. Like NONE. They do not return email, nor do they respond in any real or helpful manner on the forums. Phone calls are a waste of time.

Overall Review: Bought this because it looked attractive for the price and amount of storage. Was going to be primarily used as a home NAS, and if I liked it enough, would be taken to work. Was a major hassle to set up, the software repeatedly hung and refused to recognize the drive. Once installed, software is buggy and offers little real functionality, and the manual and documentation are awful. Finally got it set up, and transferring 300 gigs of music files took 37 hours. Yes, you heard that correctly...37 HOURS. After about 2 months of working fine, I open windows one day and see that my NAS is no longer recognized. After a ton of troubleshooting, and attempts to reset to factory settings, no luck, and it starts spitting disk format errors out, and control buttons die. Repeated attempts (over a dozen) to contact Buffalo Support via email and phone have either gone unanswered or resulted in runaround and no fix. Bought a Synology instead and it just works. Never will I buy a Buffalo pr

Pros: WHen working, I got almost 20,000 in #dmark06 with 2 in Crossfire

Cons: These cards do not run at advertised speeds. When I boot these cards up and run them for either benchmarks or gaming applications and monitor and record their speeds, even under the most extreme load their core clocks never exceed 835 and their Memory Clocks never exceed 1200 mhz (1.2 Ghz). So, basically, they run at 1/2 of the advertised memory clock speed. They are incredibly unstable cards. Even with fans engaged at 100%, they overheat very quickly. Random freezes, crashes, corruption, GPU failure, artifacting, etc. are common. HIS HAS NO REPRESENTATIVES OR CONTACTS IN THE USA....ONLY IN CHINA. NO PHONE # FOR SUPPORT. YOU HAVE TO COMMUNICATE BY EMAIL WITH A THIRD PARTY INSURANCE COMPANY CALLED 'LEXY PACIFIC'....AND THEY ARE INCOMPETENT.

Overall Review: Read my other 2 reviews. After RMAing 2 of these, being refused reimbursement of return shipping, I waited 7 weeks to get them back. When I got them back, basically same issues still present. I have tested them against a Sapphire 3870x2 and an Nvidia 8800GTX. Both of those other cards run great with minimal to no issues. Contacted HIS a second time. They refused to respond to 4 different emails. Finally got someone, who basically told me that they'd already RMAed 2 cards, and that they don't believe that I'm telling the truth and that they're not going to help me. I am going through my product replacement program to replace these cards. I have also contacted an attorney and am escalating this to a legal issue. These cards have known issues, and, according to my attorney, this company is in violation of several federal laws. There is going to be a class action suit very soon, for all of us who have been totally shafted by this company.

Pros: None that I can see. This review is a follow up to my previous review, so go read that one first, then come back here.

Cons: These cards are buggy, they do not run at advertised speeds, HIS customer support is TERRIBLE, the cards overheat quickly. Even stock out of the box there is ghosting and these weird light glare flashes. I have been through 4 of these cards now, and they have all failed.

Overall Review: So, I sent back 2 of these because of an overheating issue (they were both fried), and after 5 WEEKS, get two new cards from HIS. So, I hook the cards up individually, test them (3dMark06), then hook them up in crossfire, test them, and all is good. Well, immediately upon starting to run games I'm noticing these weird artifacts, etc. Then, the cards basically freeze, causing lockup and requiring hard reboot. I can run with a Geforce 8800 or an Sapphire x2 all day, but when I go back to these cards, it's problem city. THANK GOODNESS I BOUGHT THE insurance through NewEgg. I am now going to try to get new cards from a different manufacturer.

Pros: Good, fast, card. Almost as good as 8800GTX but cheaper. ATI Catalyst drivers 8.2 and 8.3 are solid. Nice looking in your case, and the fluorescent reactivity on the card case is very cool. Heatsink / Fan design is very good....on the models where it works (see below).

Cons: These cards have a known fan / BIOS issue that has affected about 40% of the cards shipped out. What happens is that the card's fan doesn't cycle up. It starts out at 25% speed (stock), but as the card comes under load or the heat in the case builds, the card's fan stays at 25%. The heat in the card builds and builds until GPU failure. Eventually, the card gets fried from overheating. This is what I found out after communicating with HIS about my cards which constantly overheated and failed. HIS has NO OFFICES IN THE USA. They also have no contact telephone # in the USA. You have to fill out a form on their website and then wait for an email from a THIRD PARTY INSURANCE COMPANY. They refuse to pay for return shipping, eve though I was told flat out that "these cards are known to have overheating issues due to a flaw in the BIOS". I will not do business with this company again. This was the first time buying from them and the experience has been TERRIBLE.

Overall Review: My system: Asus Maximus Extreme, Q9650, 2gigs Corsair Dominator PC1800 DDR3 RAM, X-FI Extreme Gamer Fatality, Thermaltake 1000W PSU...all from NewEgg. I bought 2 of these to go into a new build. 1 is totally fried and the other is unusable....now I have to wait for them to get it together and ship them back. I've been waiting for 2 weeks since I shipped them (UPS 3day), and I still don't have any word on when I'm going to have my cards back. I'd say go with a company that has USA tech support and a telephone #, and better customer service track record. HIS has failed in virtually every phase of this process for me.
