2 year old PC (ancient, right?) and not a glitch, exept for the texture problem which has been debated (and debated, and debated). Anyone remember WoW right after Beta?
Go and try the next WoW-Panda-expansion and come back once the major bugs in SWTOR have been worked out (you'll be back). Blizzard isn't trying anything new, so you won't be at risk leaving your comfort zone for a few bugs and gameplay-issues.
