Computer Problem: PC specs question

i was told that to find out your specs on Windows Vista you had to search dxdiag on your computer. i did that, but there are several pages there and i'm not sure which ones to post to find out if i can run certain games/emulators like Tales of Legendia for PS2

Na, you don't do it that way. You do Run -> MSinfo32. Or you can Right-click My Computer -> Properties.
