Do not use professional cards for gaming. The driver optimisations give woeful performance
compared to proper gaming cards. Gamer cards are called as such for good reason. Likewise,
pro cards are best for pro tasks. The optimisations in the drivers are completely different, eg.
2-sided textures in gaming scenarios vs. anti-aliased lines in pro tasks.
Note though that, for Viewperf specifically, excessive CPU/compute power is not required to
obtain good benchmark scores with a particular card. I've tested a Quadro 600 with a wide
range of systems, from simple dual-core i3 up to dual XEON X5570 Dell T7500. The best results,
for the
Viewperf suite that is, were obtained with an overclocked i3 550 @ 4.7GHz. See:

Note that the scores are better than those given for the Quadro 600 in this article.
Impressive data from the V3900 though. AMD have done a good job there.
So, if you're operating on a budget, and doing tasks that mirror what Viewperf tests (it's
not realistic for all scenarios), then you don't necessarily need big compute power (a multi-
CPU workstation is a waste in that sense), but good RAM is wise and definitely use a pro
card, not a gamer card. I've tested various pro cards for gaming tasks and the results were
not pleasant (3DMark06 mainly). See:

What Viewperf does not test are tasks that place significant demands on both CPU and GPU
resources, and RAM aswell, such as GIS, medical imaging and others involving huge datasets.
As always, test with your intended task; don't rely too much on benchmark numbers alone.
To
design concepts, you'll get the best general performance from an overclocked Clarkdale,
not the i3 2120 which is fixed. Or for additional multi-core rendering speed, use an oc'd 2500K or
equivalent such as an i7 870 (2500K is cheaper now though), but an i3 550 will cost 60% less which
means additional resources can be devoted to a better GPU (the usual tradeoff to consider). I have
additional results here:
