I'd personally say, get the PC version since, like hadrian said, this game was designed for PC. In general, if you have a multiplatform FPS released on PC and other next-gen consoles, then I'd definitely get it on PC, since IMO the mouse/keyboard is a lot better than the gamepad setup... Well maybe not if the game was developed on console then ported later on on PC, it might feel awkward...
On the PC version, you will also get the achievements (and bragging rights !
), like on the X360 version. I have no clue about the PS3 version though. So if you have a decent enough PC, you should be able to run it without any problems. Here are the system requirements for TF2 (taken from Steam):
Minimum: 1.7 GHz Processor, 512MB RAM, DirectX® 8 level Graphics Card, Windows® Vista/XP/2000, Mouse, Keyboard, Internet Connection
Recommended: Pentium 4 processor (3.0GHz, or better), 1GB RAM, DirectX® 9 level Graphics Card, Windows® Vista/XP/2000, Mouse, Keyboard, Internet Connection
So this game is not really a resource hog, it'll play well on "semi-old" PCs. Just so you know, I have an AMD Athlon 64 3500+ CPU (2.2 Ghz), an nVidia Geforce 7600 GT graphics card and 1 GB of RAM (not even on dual-channel, pieced together with old RAM), and I can play TF2 with
ALL the graphics settings on (including AA and HDR), and it runs without any slowdowns. But I heard that Portal is the most demanding of all games in terms of hardware.
And I don't know about the number of online players of TF2 on the console versions... I mean, 360 owners are probably still all over Halo 3
But on the PC version, yesterday there was around 11,000 players of TF2 (according to the Steam stats), bested only by the (unkillable) CS... *sighs*
And my last point: the PC version costs around $10 less... If you can, buy it on Steam since you'll benefit from the high value of the Canadian loonie, like I did
The game in Canadian retail stores is a ripoff compared to the low price in the US stores.
But either way, the important thing is that you get the Orange Box and get to enjoy the great value of all of its games (especially TF2 !), no matter what platform you are playing it on
