We've tested five HD 5770s from the leading manufacturers against each other to see which hits the price/performance sweetspot when it comes to mid-range and high-end gaming. We also cranked the settings up (HDR, Anti-Aliasing, reflections etc) even at middling resolutions, to see just how capable these cards really are.

We tested each card using the following games and settings:

Heaven 2.1
1900x1200, 8XAA, 16XAS, Extreme Tessalation

Just Cause 2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings

Far Cry 2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings

DiRT 2
Mid-range: 1680x1050, 8xAA, 16xAF, High setting
High-end: 1920x1200, 8xAA, 16xAF, High settings

The HIS HD 5770 offers gaming performance that is largely equivalent to the other 5770s we've tested. It performed around as well as any other in our Heaven 2.1 high-end tessellation tests, slightly better than most in Just Cause 2 at 1680 x 1050, although it was the worst performer in Far Cry 2 at 1680 x 1050, which seems odd. However, that performance differential is so marginal – less than a frame per second – as to be negligible. In real-world terms you won't notice the difference.

But, like the rest of the 5770s on the market, it's not really cards with the Juniper GPU that are the competition. If we put DX11 aside for the moment, it's Nvidia's last-gen, DX10-supporting GTX 260 that offers the strongest competition.

And due to a series of price-cuts to bring it in-line with ATI's 5000-series mid-range offerings, it can now be had for as low as £133, if you cast around the online retailers. You don't get tessellation or that improved multi-threading support, but you do get the kind of grunt that, with historical features such as AA and AF, outperforms the 5770.

So it's really down to a question of price and features. Is this the best 5770? Not quite. It underperforms against its peers in some tests – but by an unnoticeable margin. But at £122, it's also one of the cheapest HD 5770s going.

So if you're mad-keen on getting a DX11 card, and you're on a budget, the HIS HD 5770 is a pretty good option.


We liked

Fully-featured in the outputs department, the HIS HD 5770 is well-equipped for three-screen EyeFinity. It's also one of the cheapest 5770s around.

We disliked

As long as you've decided that a Juniper-cored HD 5770 is for you, there's little to dislike here.
