If we're to believe the information posted on UK etailer OcUK’s website, they should have stock of the 1GB Radeon HD 2900 XT cards on the 28th, that’s in 10 days time.
The card is most like from Diamond, but OcUK is selling it as an OEM product. It’s 9.5 inches long as expected.
The core is clocked at 740MHz with the memory at a mighty 2GHz DDR. This makes it the fastest Radeon HD 2900 XT when it comes to memory speed, although the GPU is 10MHz slower than most 512MB cards.
This card should be the choice for anyone that’s running a screen with 1,920x1,200 resolution and at £328.99 inc VAT, it’s not a terrible price premium to pay. Although you can pick up OcUK’s 512MB card for a mere £234.99.
