I believe you are asking if that hardware options can run crysis at decent fps, or performance, and the answer is no.
You need at least 8800 gtx or above to run crysis in decent settings and that's just the GPU.
I would recommend u to get a dual core if you are short on budget. Instead of Intel Quad, get a dual core with higher speeds on each core, since the game might not use all 4 cores.
3GB RAM is decent, but what is the speed (like 800MHz, 1066MHz etc)?
Are u building you own or buying from a brand?
