Introduction
ATI's recent introduction of the Radeon HD 3870 X2 unleashed a potential teraFLOPS of performance from a single graphics card, albeit built around two GPUs.
NVIDIA's GeForce 9800 GX2, due to be released imminently, promises much the same, but both will cost as much as an entire PC.
Being strong across the board is good, but you need to be ultra-competitive in the discrete low-end sector, where folks looking to upgrade their machine from integrated graphics will inevitably look.
So what kind of 2D and 3D performance can you get for just over £50. Let's find out as we take a look at two retail Radeon HD 3650 cards and put them up against NVIDIA's GeForce 8600 GT.
