Rogue Leader :
That board has 1 PCIe 2.0 x16 slot which YES will run that card.
However that board is older as are the processors, even the fastest processor for it will bottleneck that cards a bit. Now that likely won't make the game unplayable but you may have to tweak it accordingly.
On top of that of course you need to make sure you have a good quality PSU to power it of course.
An i5 2500 would run a 970 no problems. You would see frame loss/performance drop by 1-5%.
PCIE 2.0 to 3.0 was a marginal increase.
If he has anything under a i5 2400, then we would see big bottlenecks, since under the 2400 is the i3 series.
