I'm using four monitors in a business situation -- fantastic productivity tool. Right now though the system (Windows 7 64-bit on a Dell Optiplex 755) is not stable, and crashes once in a while. This is traceable to the other vendor's multi-monitor video drivers (cards are actually PCI). So, I've settled on the FirePro 2450. And does both VGA and DVI (cables/converters included).
1. THE BIG QUESTION PART ONE -- PCI 1.0A compatibility, i.e. will the 2450 card work in a PCI 1.0.A slot? You can find lots of people who say "PCI Express is backwards compatible and you shouldn't have any problems" -- and a few people who say "PCIe 2.0 cards don't work on PCIe 1.0A" slots.
2. THE BIG QUESTION PART TWO -- Then there's the bandwidth question. This is not for gaming. But for four 20" monitors (say max 1920 X 1080 resolution), will there be a bandwidth issue through the PCIe 1.0 slot, even if it is technically compatible.
CLARIFICATION: There are two different versions of the 2450 card, the x1 version (100-505841) and the x16 version (100-505840). Both are $ 249 Canadian dollars from NewEgg. Apparently both are PCIe V 2.0. The 2460 card does DisplayPort output, which is nice, but I don't need it now -- it is apparently PCI V 2.1.
I'm thinking if this works, it could be really nice -- it's surprisingly difficult to get four monitors on this machine. But there are huge numbers of people who'd like a technically viable and affordable solution for this. And who just have an older PCI slot.
So, I'm hoping someone can verify before I actually buy the card and adapters.
A big thanks! I'll report back if I go ahead.
