Onboard GPU vs dedicated GPU of similar performance?

Odd question, but I'm building a cheap workstation (no gaming) and I was eyeing off the older Quadro models (Quadro 600 & NVS 315) for a GPU. However, these are quite close in performance the onboard graphics card: http://www.videocardbenchmark.net/compare.php?cmp%5B%5D=2808&cmp%5B%5D=91&cmp%5B%5D=2451
Is there still a point of using one of these graphics cards if the onboard one does a similar job?

In general, is there a point of installing a graphics card that only performs about the same as the onboard graphics card? (assume both give the same display output ports)

No, not really, there is no point. The idea of the separate videocard is to add capability that you need but that your integrated graphics is incapable of performing. So then what you might want to do is go down the list of software you plan to run and make sure your HD 4600 is enough.

Two potential arguments in favor of the videocards are they have their own memory, and something like a Quadro is designed to give a high quality image output. These benefits are not that impressive if you have plenty of system ram, so sharing is no big deal, and if your use doesn't require the best image quality. If, for instance, the monitor you use is of typical consumer quality, then the Quadro has no real advantage in image quality.

Thanks, that makes sense. The only point would have been the Quadros were "certified" but the HD 4600 would have coped anyways. I should have enough ram for now so I'll save my money for a better graphics card like a K620 down the line.

Cheers!
