configure workstation for scientific computing

I'm evaluating RHEL Workstation 7.0 for possible use as an OS for computational physics. I would welcome any links to existing case studies where RHEL Workstation has been used for scientific computing, or any documentation that includes suggested settings for configuring RHEL Workstation for scientific computing. The hardware will be dedicated to this single use, and will primarily involve Mathematica 10 and an Oracle 12c database, with fairly high resolution graphics a key component. Any help would be much appreciated!

I do have one comment from my evaluations so far. RHEL Workstation 7.0 does not seem to have a flexible way to handle high resolutions displays. I'm using a Lenovo ThinkPad 540 with screen resolution of 2880x1620. At this resolution, text is tiny. Ubuntu 14.04 has a nice addition to their Gnome Display feature that let's you scale the menu and title bars. So far I've not found anything comparable in RHEL. Am I missing something?

Thanks very much.
