Another upcoming custom-design R9 290X card is PowerColor's Radeon R9 290X LCD edition. This model features a full-cover watercooling block manufactured by EK Waterblocks (EK-FC R9-290X). The card's PCB seems to be the reference design though, and we also don't know anything about the cards clockspeeds nor pricing.
The block appears to be factory-fitted onto an AMD reference design PCB. PowerColor didn't mention clock speeds or pricing, although given the block's $145 aftermarket price, one can't discount the possibility of a $120~150 premium over the $549.99 pricing of the R9 290X. PowerColor could launch the Radeon R9 290X LCS, along with another air-cooled non-reference design card a little later this month.
