The Cards (contd...)
The MSI R5670-PMD1GB (MSI R5670) is a plain-looking card that employs the same distinctive sharp-edged cooler that MSI commonly use for its budget and mainstream graphics card. Specifications-wise, it's got nothing to shout about either, sporting 1GB of GDDR5 memory and reference clock speeds. On the software end, the MSI R5670 comes bundled with MSI's popular Afterburner overclocking utility. We have had good experiences with this overclocking tool, so hopefully it'll allow us to push the MSI R5670 further in our overclocking tests later.
PowerColor HD 5670 PCS+
Like the Gigabyte HD 5670, the PowerColor HD 5670 PCS+ comes slightly overclocked at 785MHz at the core and 4000MHz DDR. Not very exciting to be sure, but the extra 10MHz bump should give a slight improvement in performance. We have also had rather decent experiences with PowerColor's PCS range of coolers, so we are expecting to see this card run with decent operating temperatures.
Sapphire HD 5670
The Sapphire HD 5670 doesn't detract from what we've seen so far, for the card comes with a fuss-free dual-slot cooler, stock reference clock speeds and 512MB of GDDR5 framebuffer. It doesn't come with any fancy utilities either, only a copy of ArcSoft SimHD IM plug-in, which upscales webcam videos to near HD quality. In all honesty, this is probably not going to be very useful.
