According to DailyTech, Nvidia has notified its partners that Hybrid SLI has been delayed. The company's delay notification states that the "drivers are being fine-tuned and sales tools are being finalized", though no actual delay reason was included. Judging by the last few months, the drivers are most likely the cause. DailyTech note that Hybrid SLI samples will reach vendors in the second half of April, while availability has been pushed back into late May.
We've been neglecting the British-pound quite a lot lately, however, it's now come to our attention that the 9800 GX2 is dropping in price right across the UK's online retailers. As Bit-Tech have observed, the 9800 GX2 was sitting around the ?435 mark at launch, though it can now be found for well under ?400. In fact, BFG and Zotac's offering can be had for ?374 at CCL. Overclockers UK on the other hand, have their usual "OCUK" version retailing at ?352 - although the warranty suffers.
