XFX HD5750 XXX & eVGA GTS450 & Powercolor HD5750 LP Review

For testing today we built a system specifically based around the Intel Core i5 760 processor which we have overclocked to 4ghz. This is easy, even with a modest cooler. We also assume KitGuru readers are a little more advanced than the average punter on the high street.

People buying these cards aren't likely to have an Intel 980X Extreme Edition processor, nor are they likely to own a 30 inch screen either. Testing will be limited to 1680×1050 and 1080p (1920×1080) resolutions in some cases which covers a broad cross section of 17-23 inch monitors – these are realistic conditions for most people contemplating a purchase.

All the latest BIOS updates and drivers are used during testing. We perform under real world conditions, meaning KitGuru tests all games across five closely matched runs and averages out the results to get an accurate median figure.

Our minimum frame rate game graphs have three main zones. These are sampled over a specific 30 interval period of time and then mapped into a chart. These are handy reference guides to detail worst case performance of the product being reviewed. When we test video cards we try to find the best combination of resolution and image quality settings while still maintaining playable frame rates.

Over 30fps is the zone most people want at all times, this means perfectly smooth frame rates with no hitching.

Between 30fps and 25fps is the KitGuru ‘Playable’ zone, although some people might notice occasional stuttering in specific scenes.

Under 25fps is classed as the KitGuru ‘Danger Zone’ which means that the game experience will be less than impressive. Settings and/or resolution would need lowered to help smooth out the frame rate.
