Your Antec case is great for a silent system but it's not really well known for good air flow. Hope you can figure something out. In the meantime I'd remove the 250 card. Dedicated cards for PhysX is not really worth it IMO (unless your primary card is from ATI). Maybe you can install a fan or something in that slot to add more airflow.
About the BC2 issue. I haven't tried the game yet on the 480s but maybe you should increase the level of AA and add HBAO on your new card. I guess the 470 won't slow down that much and it'll show the difference to the 260 a bit better. BC2 is not really a taxing game, I played it on a 8800GTX for a while and it performed pretty good in DX10 with 2x AA.
I'll probably take the 250 out after I finish playing Cryostasis... or if I decide to wait on that game, I'll just take it out now.
There is a huge performance boost by having that card do the Physx in that game, even on the 470... but the game is just so ridiculously packed with effects and super high-res normal maps that the frame rates tank, regardless of the Physx load.
Its looking like I'll be getting a new case fairly soon. I really love how solid and quiet the P180B is, but wiring, cooling and space are incredibly bad. Its just not a modern "gamer's" case. It would be better suited to a sleek office machine with a high end CPU since the air circulation is almost entirely focused on the CPU area.
I think I'll go make a thread about this now...
