How good will Crysis run on this rig?

15fps@very low... maybe
don't even try it lol

Your system will only be hindered by the graphics card. Why not purchase a new one? 9800GT perhaps?

You won't get far with that. Might i suggest a 4850 or 9800gtx?

Most of your rig is fine ... the only thing that will hold back your fps is your video card .... it's not really a gaming card. So I agree with kari .... don't even try it unless you really like slideshows  

8600 1gb? holy cow, the marketing shennanigans. these people have no soul.

See if you can sell that card to someone else for like $60. then spend the extra $40 on an 8800gt

1gb on an 8600? is it? you got a nice setup... HD 4850 will be great... Even the 8800GT will be fine at the resolution.

I used to have an 8600gt, and I played crysis once just to see... If I remember right, it got like 30fps on the low settings.

^^oh so I underestimated it a little, sorry about that, won't happen again.  

no problem

With SLI 7600s when I had em I ran crysis (not warhead) on medium settings no problem at 1024x768 I don't remember the frame rate but the game ran smooth so it was over 30. With an 8800 GT I can run Crysis on high settings @ 1280x768 and Warhead at the same level at the same resolution.

crappy card!
get an nvidia card like the 9800gx2 gtx260 more optimized for crysis then ati cards. 4870 is better in most games slightly but loses in crysis.

yeah get a 88/9800GT if at all possible, at that resolution you should get 27+ fps with med-high settings.you wont get much higher than about 36 fps max but it will stay around 30 or so with med to high settings.

at 1440x900, a 8800 GT can run all high @35fps or so depending on the section. a 9800 GTX or 4850 would fit you well.

They should shoot whoever decided to sell the 8600 1GB DDR2.
