If you are not into gaming then that is more than ample for your needs.
As for the connectors? I wouldn't allow that to be a consideration for the following reasons,
1. DVI to VGA adapters are very cheap and work perfectly with KVM's. Some cards actually come with one included.
2. I used to think like that too ferg but if you think again the cards with two DVI connectors are even more productive considering you can also get the DVI to HDMI adapters for them. It's a clever move by manufactures I think?
As for the power consumption? You can check that by using This Site, just select everything you propose to have in your rig and it will tell you your power supply requirements.
Sometimes I wonder about gamers and their quest for high end graphics, not only do they need a mortgage for some of the cards but they need to be connected to the national grid to run them too Then they are always bitching about lag and jitter. I'm of the opinion that PC's are for lots of things but if want to game buy a console? You can get one for a couple of hundred bucks as opposed to a thousand + for a reasonable gaming rig (sorry gamers)
As for the DDR3 memory on the card? That's not an issue either as it relates to the GPU memory and is totally independent of the Motherboard.
