Top Customer Reviews

Pros: Quiet, ran smoothly under ultra settings in Starcraft 2, decent tech support, limited lifetime warranty, color scheme

Cons: Failed 2x, did not work with 3 displays even with latest drivers (attempted both DVI ports and HD port). It would only work with HD port and DVI or DVI with DVI for dual displays. After 11 months of casual use for gaming the card started to give me display issues. Windows would boot, but no display from card or it would display then flicker with lines and then no display. Also for video rendering my CPU intergrated video was signifcantly faster (sorry no data specs).

Other Notes: Bought this as an upgrade as my other card caused lag getting me pwned in SC2, gave me a Windows 7 score of 7.4. Biggest issue right now is customer support responding to my concern that they sent me the wrong card (lower grade HD-675X) despite the box labelled as HD-677X they sent it with. The first RMA lasted me roughly 7 months then had to RMA due to same issue and am now awaiting response after 3 attempts for the 2nd RMA. Would I recommend this to a friend? Highly unlikely mostly due to having to RMA 2x within approx 7 months and the lack of response from customer service. Tech support was good up to this point however they have not responded to my concern that I was sent the wrong card. I'll post update later.

Decent low budget grafics card. I originally purchased one when Skyrim came out and it ran great! Still doing wonderful. I got a second to crossfire and so far no issue. Very pleased with this model.

Works good for an older card. Can play most older games @ 1080 frm Mid to high settings. Usually frm 20fps to 50fps...depending on games of course. Overall great card!
