really quiet
Sleek design
Good price
Lifetime warranty
Honestly I bought it for the design. Since I can't afford the 7970 version of this card I bought this one. It runs really cool and I have no complaints whatsoever. Definitely recommend to buy as this is one of the nicest looking and quiet cards out there in this price point.

Experience: 8 Months

Very Quiet, Price for performance ratio is great
Connections are tight at the back, might just be my case though.
I have been using this card for awhile, I play bf3, Skyrim, BL2. all on max or high settings.Im actually ordering a second one to setup crossfire.

Experience: 5 Days

- Good construction with dual fans.
- Free games download with purchase.
- not working for the rebate.
One of the good value graphic card for light to medium type of gaming. Don't count on the rebate for your buying decision since the site seems to have problem for other people.

- Quiet, can't even hear it over stock case fan
- Blocks off a PCI slot
- CD didn't work, had to download drivers from AMD website
It's super quiet! Can't even hear it over case fan. Be warned that it's rather large, takeing up an extra PCI slot, so might not fit on certain microATX builds. So far I'm happy with it!

-Was a good upgrade from my hd4850 and runs great at my monitor's resolution of 1680 by 1050
-Price (on sale)
-cool temps from the Double D's
The game bundled with the card was Nexuiz which is listed as a $50 value. The game is currently $10 on steam and was on sale for $2.50 when I purchased the card. I am not removing any stars as the game was not the reason why I purchased this card but it should not be listed as a $50 value.

Also shortly after my purchase they added Dirt Showdown to the bundle so I just barely missed out on receiving another game with my purchase. But that's the luck of the draw I guess.
I am still giving the card 5 stars as the product itself is great and I am quite happy with my purchase.

And I look forward to overclocking as its dual fan cooler design looks quite extensive.

The card also looks to have great crossfire potential and I am likely to pick up another one in the future.

Okay peformance/dollar. Best peformance/watt. Runs cool and very quiet. Looks expensive.
Not the best value. Garbled texture problem with some games.
Bought on sale plus MIR and free game.
Didn't want to buy Radeon but Nvidia didn't have retail GT640 with GDDR5. I really wanted to buy geforce...but this does the job nevertheless.

Experience: 2 Weeks
- XFX quality and reliability
- Sleek custom cooler
- brand new 7xxx series from AMD
- LOW power consumption
- not the best price/performance.
This is a decent graphics card that can probably run most games at better settings. You are paying a premium as this card is new to the market w/ newer technologies. If you want to best bang for buck, I would stick with the 6850/6870 for the same price.

Experience: 3 Days
Extremely quiet, very low temperatures, consumes very low power, handles 10-15% overclocks easily. Cooler looks sexy.
6850s & 6870s are a better value proposition for gaming at the moment.
If gaming is your sole focus, a 6850 or 6870 would probably be better at the same or lower price point.

With that out of the way, I purchased this at NCIX's first annual tech fair for $119.99 and I am extremely happy with my purchase. I think this is the best looking 7770 available today and I appreciate the advantages that the 7 series brings over the 6 series. Currently have this overclocked to 1100/5000. Wouldn't hesitate to purchase this again for around the same price.

low cost and good performance
no DVI to VGA adapter
Have this VGA card for my friend's PC when it is on sale. Quite good in terms of the prices. Working well so far but the next time I would like to buy other company's VGA card because it doesn't include the DVI to VGA adapter which would cost me $5
