By TechRadar, published 17-04-2011

The change in the multi-GPU game over the last eighteen months or so has been dramatic. It's been a long time coming but the technology is finally coming of age, but there's now a real reason to be dropping a second card into your home system other than just bragging rights: straight performance.

With a combination of flaky driver support, dodgy hardware implementation and frankly shoddy performance, it was hard to recommend anyone part with the extra cash for the second card. The diminishing returns you got from dropping in that second GPU made it a very expensive and ineffectual luxury. With driver improvements, and far better graphical silicon coming from both the giants of the gra...

ATI Radeon HD 5770 1GB
