Here's the first picture of the PCB under the hood of MSI's Radeon R9 290X Gaming OC graphics card, which was unveiled in Japan, over the weekend, and which was detailed in a slightly older article. It turns out that MSI will use the same board design (including the back-plate) on both the R9 290X Gaming OC and the R9 290 Gaming OC, both of which have been put up for pre-order by Canadian e-tailer NCIX. The R9 290X Gaming OC is priced at $699 CAD including taxes (US $660); while the R9 290 Gaming OC is priced at $529.99 CAD including taxes (US $500).

The PCB itself is a slight variation of MSI on AMD's reference design. The layout is identical, but there are subtle differences in component choices MSI made. For example, it ditches Coiltronics-made chokes for MagicTech. Appears to use SK Hynix made memory chips (instead of Elpida on a vast majority of retail R9 290 series boards), etc. It also appears to retain dual-BIOS. According to NCIX, both cards will feature untouched memory clock speeds of 5.00 GHz, yielding memory bandwidth of 320 GB/s, but feature 5-7 percent overclocks on the GPU. The R9 290 Gaming OC features GPU clock speeds (possibly PowerTune boost) of up to 1000 MHz (vs. 948 MHz reference), while the R9 290X Gaming OC features 1040 MHz.
