4670 Crossfire - The secret to budget gaming?



Gigabyte HD 4850 CardsSumming up the performance of a 4670 Crossfire configuration is certainly no easy task. In benchmarks such as Call of Duty 4 and 3DMark05 it performed admirably often beating the HD4850 1GB and in some cases even the factory-overclocked HD4870. In most other benchmarks the Crossfire configuration went head-to-head with the HD4850 often winning at the lower resolutions but choking once high resolutions or texture filtering were applied. 3DMark Vantage and Crysis on the other hand; were a total disaster, with the Crossfire setup showing serious signs of strain and producing almost laughable results in comparison to  the 4800 series cards and of course the PhysX enabled GTX260.

In terms of value on our CPF scale the HD 4670 setup positioned itself just above the HD 4850, but still quite a way below the HD 4870 and GTX260 in most benchmarks. Add to this the inconvenience, additional noise and flakey support for Crossfire among game developers and it's pretty much safe to say that two 4670's in Crossfire are NOT the secret to budget gaming and a better investment would be in the HD 4850.

However, if you already have a HD4670 in your machine and are looking for a way to crank up the gaming performance at minimal cost, dropping in an extra 4670 will certainly achieve the desired effect and allow you to game alongside the 'big boys'....well at least in a handful of titles.

The Good
- Some games show great improvements.
- Cheap way to substantially improve gaming performance if you already own a single HD 4670.

The Mediocre
- Takes up extra space inside your system.
- Generates more heat and noise.
- Costs (a little) more than a single HD 4850.

The Bad
- Performance in some games is terrible.
- Cannot compete with the HD 4850 at high resolutions in most games.

Thanks to Gigabyte for providing the HD 4670 and HD 4850 cards for todays review.
