As mentioned earlier in the review, our main focus today is going to be on the performance and value of the Sapphire HD 4830 with an overclock applied. These results will be compared to both the stock HD 4830 results, a generic HD 4850 and an XFX 9500GT thrown in for good measure as a representation of a once similar priced card from the green team. To ensure that each of the graphics cards has plenty of room to 'shine', the following overclocked test system will be used to remove the chance of any bottlenecks outside of the GPU.
Intel Core 2 Quad Q6600 "G0" 2.4GHz @ 3.6GHz
ASUS Rampage Formula X48 DDR2
OCZ Flex2 4GB (2x2GB) PC2-9200 5-5-5-15
Tuniq Ensemble 1200w
ASUS MK241H 24"
AMD Catalyst 8.10 / NVidia ????
