Each card boasts a matching 1GB of GDDR5 RAM, but the higher bandwidth we see here comes as a result of the 6870's wider 256-bit memory bus, which doubles that of the 6770's. When it comes to hitting higher resolutions and allowing for additional anti-aliasing, the HD 6870 benefits from its peak memory bandwidth of 134.4Gbps, compared to the 78.8GB per second available on the HD 6770. On paper, the swap appears to justify the extra expense. Could a straight swap from the 6770 to the 6870 elevate us to the ideal of 60 frames per second gaming? Curiously, while the 6870 has dropped significantly in price, our initial 6770 has actually gone up by around £5 to £10, making the extra expense a mere £20 to £25 extra overall.

Our initial spec produces high frame-rates at 1366x768, but we were effectively limited to 1080p gaming at 30FPS. And for Digital Foundry, it was a chance to re-evaluate our recently constructed custom PC. If you're running an older PC that's running short of horsepower on the latest games, at this price, a card with the pedigree of the Radeon HD 6870 looks like a bit of a no-brainer. And this is just the beginning - as price-cuts begin to kick in on AMD's replacement 7xxx line of GPUs, we would expect more mainstream online suppliers to follow suit. Having bossed the £120-£140 price bracket for some time, the 6870 is starting to get some serious price-cuts, to the point where - at the time of writing - the card can now be picked up brand new on eBay for under £100, or at similar price-points from certain e-tailers. The classic Radeon HD 6870 - for a long time the enthusiasts' favourite, and still a very powerful piece of kit - is reaching its 'end of life' and if you keep your eyes peeled, you can pick up a superb GPU at an irresistible price. performance, but recent adjustments in the AMD range have made us rethink.

In choosing our parts, the Radeon HD 6770 looked to offer the best trade-offs in price vs. In putting together the Digital Foundry PC, we were looking to get the nucleus of great computer, a taste of the high-end for entry-level money.

Choosing your next PC upgrade is always something of a balancing act - a fine art in extracting the maximum gaming performance at the best possible value: the highest FPS per GBP, if you will.
