I was wondering it was feasible to upgrade my system, or whether I'm better off buying a completely new system in the future. During the summer, the company my father works for was purchased by Danaher, and as a result, the building was closed (thankfully he kept his job). Danaher siphoned what they wanted from the building, and allowed the handful of employees that didn't lose their job to pocket what remained.
My dad came away with quite the load, one of which was a computer that he gave to me. It has an Intel Xeon E5405 2.0GHz CPU, 4gb of Ram and a NVidia GeForce GTX 275. I've been out of PC Gaming for a LONG time until getting this computer (I was last in it when the ATI 9800 Pro was the best video card), so I have no idea if these specs are good are not. All I know is the computer is capable of playing games like Skyrim, Dishonoured, DmC, etc. at very good settings without a hitch. This is the computer:

I'm assuming I could use more RAM, but unfortunately ram for this computer seems to be expensive. I'm not sure how much ram/how many ram slots the computer actually has, could someone tell me by looking at the above PDF?
Is there anything I can do to squeeze some untapped potential out of it, or should I just ride it out and purchase a new computer once I come by the money?
