The HIS HD 7750 IceQ X Turbo is an evolutionary upgrade to the AMD reference HD 7750. Instead of a single slot design, which only uses PCI-E slot power, HIS has put a bigger dual-slot cooler on the card while also adding a 6-pin power connector for improved power delivery. These changes enabled HIS to ship the card with a 100 MHz overclock on the GPU, which, in our testing, translates into a 7% performance improvement. Unfortunately, memory is not overclocked, which would have provided easily attainable performance gains. Don't expect any miracles though, HD 7700-class cards are designed for entry-level gaming at lower resolutions and reduced details settings. Gaming at 1680x1050 should be ok, but full HD gaming will be too slow with the HIS HD 7750 IceQ X Turbo.
The HIS IceQ X cooler provides excellent cooling performance, but does so with more noise than is necessary. It looks to me like HIS did not properly optimize their fan settings in the BIOS, so the card emits more noise than is required since the fan runs too fast for the heat output of the card.
Overclocking works extremely well and provides more than a 25% real-life improvement. For a card in this performance class, overclocking is not that important though - serious gamers just have to shell out a bit more cash.
Talking about money: HIS says the card will retail for $120 which is, in my opinion, a lot to ask. The cheapest HD 7750 goes for $90; 30 bucks less! The cheapest HD 7770 cards start at $120 and provide 20% more performance, even without any overclocking. HIS really needs to reconsider their price point and work on fan settings to reduce noise levels. Other 900 MHz HD 7750 cards sit at the same $120, so HIS is not the only one to blame.
