Oh well... I'm not in any hurry to play them.I guess you can't. They list them individually with the price when viewing the Orange Box on steam but only list the packages they are in when you click on the game.
My guess is that the video card would be the same price. ATI/AMD probably paid a lump sum to Valve to promote more video card sales. So the game is already paid for, not by you but by ATI/AMD. And it's for promotion so they would not include the price back into the video card. I know that was the case back with HL2 and 9800 Pro video cards.
I'd hazard that the term 'beta' is really an excuse to encourage the hardcore such as our good selves to purchase it through Steam and play it early, rather than buy the retail edition when it hits the shelves (retail = less money for Valve vs Steam). Given Valves track record I expect TF2, Portal and HL²Ep2 have all been tested to death under a variety of conditions.Pre-purchased'd.
and Okidoki brings up a good point...if TF2 is in beta, doesn't this indicate that it isn't finished yet? Maybe we're testing for the first patch after release?
