Building a small form factor system or an HTPC? Overclockers Club has the low-profile Sapphire Radeon HD 7750 in house for a little review action. After a few iterations of testing and tuning I ended up with an overclock of 440MHz on the core (+55%) and 315MHz on the memory (+28%). This is an absolutely massive overclock! The temperatures, as you'll see later, leave a bit to be desired but aren't terribly unreasonable for such a tiny card (though you'd likely want a larger cooler if you ran these clocks 24/7)."
