PS3 has better textures, 360 has better framerate. You decide from there.

PC

" @Three0neFive:  Your 10 years to late...... "

buy it on the pc if yours can handle it. it's basically a pc game ported to consoles and released at the same time.

PC or bust

"If your PC can handle it then without a doubt get it on the PC. I hear they adapted the system well for a controller, but that type of game is much more suited for a mouse/keyboard setup. Plus there's a decent user mod community out there for free content to the main game, bug and balance fixes plus full extra stories.  If your system wont cut it then I'd go for the 360 version based on what I read in reviews and comments. "

PC is definitely the best way to play this game, but I played it on 360 and didn't have a problem with it. 

I always buy mutli plat games on my 360.  I reserve my PS3 for exclusives.  I don't think it matters what  console you choose...  they will both look and play great.

PC has smoother more efficient gameplay imo, but I have it on the 360. I'm more partial to consoles, but either way you get a great game.

PC is by far the best, but that said i got it for 360 cause my PC couldn't run it and i had a VERY good time with it.  It is a great game no matter the system you play it on. 
 
that said, to answer your question, i'd get it for 360 over ps3 due to less pop-in and better frame rate (but as said elsewhere, PS3 does have slightly better textures, prolly the reason it has poor frame rate)

I have the Game on both PC and 360 as many have stated this game is a game made for the PC. While I didn't have a problem with the radial menu they have. I feel that there is a more tactical element to the game when played on PC 

I play it on my mac, but wish I had it for 360....theres something about kicking back in the ol recliner with a controller in hand...
 
Edit: but, the interface on the pc version kicks the ass out of any interface they could make for a console....so easy to cast spells on the fly, etc

Its a PC game. The ports are shitty. Anyone who recommends them has no point of reference with the PC game. You might as well be playing the Wii version of COD4 if you're that clueless.

The ports are fine, but the game is definitely better on the PC.

As someone who owns the PS3 and PC versions, and being mainly a PC gamer for the past couple of years, I can say I prefer the PS3 version.
 
I don't know, maybe it's because it was made easier (I'm pretty sure it was, comparing the two personally), or maybe I just preferred the controls. I didn't read the thread, so sorry if this is no longer relevant.
 
@ryanwho: I guess I'm an exception to your theory.
 
@amoremono1: I find it easier/faster to cast spells on the PS3 version. I guess it's just preference. I'm not a fan of using the number keys.
