I am going to purchase a used Dell XPS 410 with 1.86 c2d, 4gbs of ram and a nvdidia 8600gts graphics card. My questions are two... (Vista Ultimate btw)

1) Will Team Fortress 2 run decently well on it?

2) How much would you think a used box like this should cost? With just a standard harddrive ( i think 120)

I consider myself a huge video game fan. Owned every Nintendo console ever, and played vast amounts of games. Love all kinds of games. I have never had a Ps2. I know that seems kind of contradictory. But here at college my roomie has a ps2. So I'm looking for games that fit two categories:

Games that I would be incredibly stupid to miss out on. Games that Defined the system

and Games that won't break the bank, because I won't have the ps2 forever.

Any help would be greatly appreciated.

And again.. I play fps, rpg's, action, fighters, puzzle
