According to the specs that I found on HP's website, your HP switch does not support 10Gb, only 1Gb on its mini-GBIC ports. You will definitely need a new switch to take advantage of 10Gb.
If you do get a switch that supports 10GBase-T, you should definitely consider the Intel X540. The vast majority of reports that I have seen say that it works great. (There was one report I found on a forum claiming performance issues, but others on the same thread said it worked fine for them.) There are also many dual-port SFP+ cards out there (such as the Intel X520) that are not too expensive and support lots of different types of SFP+ connectors. Although Intel does not make a 10GBase-T SFP+ itself, there are third parties that make it. You would use one of those to connect to the 10GbE feed into the rack and then a regular fiber SFP (or the option listed below) to connect to the switch. To connect the pfSense to the switch, I would probably use a Direct-Attach cable (DAC) instead of fiber or Ethernet. Approved Optics <http://approvedoptics.com/> is a company that makes many OEM network connectors under contract and they also make their own versions of them at significantly reduced prices. Their DAC Finder <http://approvedoptics.com/dac-finder/> tool lets you order a cable that has SFP+ ends for different manufacturers (for example, an Intel end for your pfSense and an HP end for your switch). There's no need to worry about fiber or CAT7A Ethernet cables; just plug the cable in (taking care to make sure it is oriented correctly) and that's it. Since you have a limited budget, I really recommend going the direct-attached route. They are so much cheaper and more resilient than fiber, and switches with SFP+ slots are often much cheaper than switches with 10GbE. For example, you can get a Uniquiti EdgeSwitch with 48 Gb ports and 2 SFP+ ports for just around $400. These are the switches I have used in many of our limited-budget installations in the past (including in a University setting like yours seems to be from your email address) and they perform well. (Note that Approved Optics does not have official Ubiquiti cables, but many on the Ubiquiti forums report that it works with Cisco and other brand cables as long as they are 2 meters or shorter. In a single rack, that should not be an issue.)
