Diamond ATI Radeon HD4850 Review Overclocked

Overclocked


Testing an ATI video card on a NVIDIA-based motherboard is a bit of a waste, especially since doing CrossfireX on NVIDIA-based motherboards is impossible and SLI is impossible on Intel-based motherboards outside of SkullTrail. The closest high-end competitor to the nForce 790i Ultra SLI motherboard is the X48 chipset at the moment and that is the motherboard used in this review. One oddity was the Bioshock results which are higher than I expected. This is probably a case where AA is not enabled in testing the ATI cards.
