[QUOTE="CoolHandLuke, post: 91487, member: 4850"] no, i was right, the tesla does bridge and is capable of SLI though it is not required. bridging with SLI would provide you with as i said bloated GPC performance, bottlenecked by the usual suspects of a computer - RAM, and hard drive. instead these tesla cards have integrated into them mini p3 computer processors, freeing CPU bandwidth to devote to running your kernel functions. so unless you are running Linux (for which NVidia has no [i]public[/i] driver support but t does for special systems like defense departments and research projects) you basically just have a very good video card, and not much else. remember: supercomputers like Titan do not use windows. if it did it wouldnt be a supercomputer. Cray as a system isnt one easily optimizable for traditional hardware, suited for tasks a normal Linux enthusiast would undertake. it was designed to be one where the core hardware ran base kernel functions, and where additional hardware ran the computational array. it was essentially designed for a supercomputer, and these arent systems you cook up and boot windows on. bottom line, you really are just spending a ton of money on a faster video card.
