"XFX 650 W XXX Edition is a very good power supply, being capable of delivering its labeled wattage at high temperatures, keeping high efficiency if you pull up to 80% of its labeled capacity (i.e. up to 520 W), a three percent voltage regulation (as opposed of 5% as defined on the ATX specification – translation: voltages closer to their nominal values than required), low noise and ripple levels, modular cabling system and a single-rail design. "

"XFX are a trusted brand in the graphics card world and a card with great performance, amazing value, and the latest technologies coming from them is bound for greatness. That’s why i’m giving this graphics card 5 out of 5 stars."

"XFX HD 5770 XXX is part of XFX's XXX series, which means that it had increased frequencies right from the factory. Usually, one can ask whether it is worthwhile to buy these through a special edition, it is usually not any problem to achieve the same levels with the usual cards. But in this case, the price differs so little, plus the XFX card clocked higher than the other cards. It may be that the nucleus of XFX's XXX Card is specially selected, just as they must cope with higher frequencies."
