Yes, however the amount of cores on a CPU doesn't determine if you can have dual displays or not.
Confirm that the BIOS firmware support the dual core CPU
A dual core processor has two processing cores, whereas a quad core has four.
A "dual core" CPU is one that has 2 CPU cores (as opposed to 1 in older computers). "Core 2 Duo" is line of (dual core) CPUs produced by Intel.
That can either mean a dual-socket machine with dual-core CPUs (two CPUs with two cores each) or a quad-core CPU (one CPU with four cores).
Dual core is the property of having two cores in a single CPU. Core2Duo is an Intel CPU that has two cores.
´Dual core' just means that there are 2 separate cores in the CPU. Intel has made dual core pentuim 4, core duo and core 2 duo CPUs. ´Core 2 Duo´ is just one type of dual core CPU that Intel has made.
A dual core laptop is a laptop that uses a processor that has two cores. Having two cores allows a laptop to perform more powerful functions and speed than if it had a single core.
Video splitter or multiple video cards
Yes & no. If they are both single-core (one processor) than yes, the 2.0GHz is clocked at a higher speed. But in the case of multi-core processors it varies...such as: A 3.0GHz single-core CPU is "equivalent" to at 1.5GHz dual-core (two processors) CPU. Or a 1.5GHz Quad-core (four processors) CPU is faster than a 1.5GHz dual-core CPU because it'd be 1.3GHz x 4 processors versus 1.5GHz x 2 processors.
Pentium D was the first dual-core cpu.
