a. If u must go Intel await the SB chipset flaw to be ironed out andgo with that else
b. 955BE - 1055T + OC on a cheap IGP chipset I do up 1055T + entry level 880G rigs and you can OC those 3.2-3.4 on stock HSF/value RAMs no issue ^^
* If you install AMD AM3 CPU on this motherboard, the system bus speed will downgrade from HT3.0 (5200MT/s) to HT1.0 (2000 MT/s) spec; however, the frequency of AM3 CPU will not be impacted. Please refer "CPU Support List" for more information.
• HyperTransport 1.0 supporting speed up to 1000MT/s
• 1 PCI Express x16 slot with x16 operation (PCI Express Bus SPEC V1.0 compliant)
In short - hit a 760G/785G/880G and for this kind of rig u have to be selective so work on fast chip and bump up RAM to 4GB-8GB The integrated graphics will do and mission critical/professional peeps go with professional class Firepro/Quadros anyways hehe
