Our Score:


We tested this card on our usual test bench, the details of which are below. We ran five games to test for performance then checked total system power consumption and noise levels both when idling and gaming. As always we ran our tests multiple times to try and ensure consistent figures then record the average.

With the exception of Counter-Strike: Source (CSS) and Crysis, the gaming results are recorded manually using FRAPs while we repeatedly play the same section of the game. For CSS and Crysis we use timedemos and framerate recording is automated. For Crysis, all in-game detail settings are set to High while all the other games are run at their highest possible graphical settings.

Meanwhile, power draw testing is done using a mains inline power meter. The idle figure is taken when the system is simply on the windows desktop with no obvious background activity going on. The load test is then taken when running our Crysis timedemo at 1,920 x 1,200 with 2xAA. Likewise, noise levels are tested using the same idle and load scenarios as above. We isolate the test bed in a sound proof box and record noise levels from about 30cm away.

We find that below about 40dB is indicative of a card that when housed in a conventional case will go unnoticed in a relatively quiet home office environment. For use in a 'silent' PC (for in the bedroom or cinema room) without resorting to sound proofing your case, you'll want a card that's lower than 35dB at idle. As for under load, above about 50dB is a constantly noticeable level that would disturb you if using speakers or open-back headphones while gaming.

It's a shame this card is noisy, it would be a great option for an HTPC otherwise.

Have you tested the HD audio output over HDMI? A patched version of PowerDVD is supposed to handle DTS HD / Dolby TrueHD in bitstream over HDMI at 24p on the 58xx family. It would be interesting to know if it works as expected, until we find out if nVidia delivers something equivalent with the 3xx serie. Maybe a passive cooling version will fit the bill?

If it's one thing that drives me away from cards, no matter how powerful they might be, it's the noise level. These things need to be made absolutely silent.

Sapphire do a Vapor-X version which claims to be a lot quieter if that's any help. It is about £20 more but that's cheaper than buying a quiet third party cooler.

Oh and it's slightly overclocked too.
