HYDRA System Lets 'Vastly Different' Video Cards Work, Play Together

Lucid's HYDRA GPU pairing technology could soon allow PC builders to incorporate multiple video cards that - hear this, ATI and Nvidia - don't have to be identical. What this potentially means, among other things, is that gamers could leverage old hardware instead of just sadly setting it aside, though paired cards must be of the same brand. HYDRA differs functionally from Nvidia's SLI and ATI's Crossfire solutions, which split rendering by sectioning off the screen and alternating frames between cards, respectively, by intelligently distributing highly specific rendering tasks between the GPUs. Instead of divvying up all the tasks equally, HYDRA will only send as many polygons or shader calls as each constituent card can handle (see right of the above pic for an example of what one of two cards might be rendering).

One of the best arguments for building your own PCs is that you make the decisions regarding parts,which means you don't have to scrap the whole system or buy sub-standard hardware from the manufacturer when it is time to upgrade. This is especially true for gaming rigs. Dell, one of the biggest offenders when it comes to this issue, has announced that proprietary parts like power supplies and motherboards will be a thing of the past.
