Anyone else worried about HL3 being announced but their PC being unable to handle it.

My pc was able to handle Alyx but idk, if HL3 comes out and this old baby (this pc is outdated) is unable to handle HL3, than oh boy.. I mean, its no secret that a lot of us PC Gamers have to update our PC and that PCs are crazy expensive. I am going to try to update my PC. Like I am a selfish fuck. If I cant play HL3, I don't want anyone else to. lmao, but seriously, does anyone else has this fear?
