I would like to run a 64-bit massive computing (scientific computing, Finite Element) single thread application on 64-bit Red Hat Enterprise Linux ES 4.

Q1. Does it make sense to buy a dual core processor?

Q2. Which of the following configurations is better from the point of view of the computational power/cost ratio?

Tyan Thunder K8WE, S2895A2NRF
1x(AMD Dual-Core Opteron 265 Box)
2x(1024 DDR400 ECC registered)
Quadro Fx 1400, 128 MB
HDD VD2500JS, 250GB, 8MB, SATA 300

1x(A64 X2 4400)
2x(1024MB DDR400 V-DATA)
Quadro Fx 540, 128 MB
HDD VD2500JS, 250GB, 8MB, SATA 300

Q3. Could you compare the computational and graphical power of those configurations?

Q4. Could you give me a suggestion how to improve configuration A or B?

Q5. Could you explain differences between Opteron 265, Opteron 165, Opteron 254, Athlon 64 X2 Dual Core processors?

Q6. I think that adding the second processor to configuration A does not bring a new power to computing if the application is single thread. Is that correct?

Q7. How can I later improve the computational or graphical power of the configuration A.

Q8. Can I overclock the Opteron 265? If yes, what is the maximum frequency?

Q9. Does it make sense to by DDR 400MHz ECC Registered CL3 DIMM Dual Rank in case of the configuration A?
