Here we see the card's cooler which is almost identical to the one used in the high end 7900 series. The XFX Double Dissipation cooler which uses GHOST technology is perhaps the best looking design we have seen to date. Improving on AMD's already improved reference cooler, the DD cooler is an all aluminium affair that has a very attractive brushed effect with black insert shrouding two fans, each having eleven angled blades with aluminium effect decal centres.



The base of the card is fairly standard with 4 memory solder points signifying this card, like the reference card has 4x256MB GDDR5 modules.



The graphics card will look great in most any pc setup and the view above shows just how much the XFX R7770 gives off the air of quality. The anodised Red aluminium insert that runs along the full length of the card certainly looks the part and will no doubt be the first thing geeks see when peering through your case window.



The input/output area features a signle dual link DVI port, full size HDMI port and twin mini-DisplayPorts. The card is capable of HDMI 1.4a including HD audio support, perfect for Blue-Ray playback. The HDMI and Displayports are 4K ready and are capable of displaying huge resolutions of 4096x3112 and 4096x2160 respectively. I like the red DVI port as it shows an attention to detail although other than looks, it operates like any other DVI dual-link port.



The card is Crossfire capable thanks to the single Crossfire tab. Unfortunately, dual card configuration is as far as it goes though due to this physical limitation.



The XFX R7770 will require a single 6pin PCIe power port with a PSU capable of delivering
around 500w. The while the HD7750 makes do without an additional power port, the R7770 requires this port due to the estimated 100w power consumption under load and so because the PCIe slot is only specified to 75W, AMD saw fit to allow an additional 75w by the implementation of a 6pin PCIe power power.

Let's delve a little deeper and remove the cooler...
