7600GS will play the game but not so well; I mean you'll have to reduce settings and play it. the 8600GT is recommended for decent frame rate (high settings)
tried playin bioshock with 7100gs ( read:without a graphics card)......framerates were too slow...but considering i was able to play a bit means ur card wld be more than sufficient for 17"
Customs is a long story had a thread on general section some time back. But now my 7600GS plan is cancelled will be getting a 8600GT so I guess should not be an issue
