Well, you can buy quad core processors (just Google Quad Core) but
whether or not it will be compatible with your current computer is something
you'll have to take up with the manufacturer.
Alternatively, you can buy a new computer.

To use all the core processors in a quad core computer,you need games or programs specifically developed to support a "multi-threaded" operation.
An Intel Quad is more specifically referred to as the Intel Core 2 Quad line of computer processors. They are multi-chip modules and quad processors and they succeeded the Core 2 Duo line of processors and have speeds twice as fast. They have twice the same clocked-speed frequency under similar environmental conditions as their predecessors and have an L2 Cache anywhere from 2x1 MB per second to 2x6 MB per second. Kentsfield, Yorkfield and Penryn-QC all had variants of the Core 2 Quad line.
The CPU of a computer used to be a single processor on one micro-chip which performed all the necessary functions. Dual (and now quad) core processors have two (or four) processors on a single chip. This means the computer can process two (or four) instructions at the same time - making it much faster.
"Dual core" implies that there are two separate instruction execution units placed on a single "die." Some use shared components, such as cache, while others have two full processors, including all sub-components. All dual core processors could be considered multi-core (which simply means multiple "cores" or "processors"). However, a tri-core or quad-core is also a multi-core. Therefore, all dual cores are multi-cores, but not all multi-cores are dual cores.
it all depends on the ram and the video card in the computer
The clocking speed of an Intel Core 2 Quad Q6600 processor is 2.4 Ghz. Clock speed refers to how quickly a processor can do a task. More information on all of Intels processors can be found on their website.
All Intel Core 2 processors are capable of running in both 32-bit and 64-bit mode.
The Acer brand, the Dell brand and the HP brand are all company brands that produce a laptop with a core duo processor. Though most have moved on to providing quad core processors.
Online reviews for the Intel Core Quad are located at many stores that sell the Core Quad. Newegg, Amazon, and HotHardware all feature user reviews from people who purchased the Core Quad.
All intel processors Pentium 4 and down were single-core, or "core solo" processors. They weren't called "Core Solo," but by what respective family they came from. Pentium I, II, III, and 4.
Dual cores have two cores, and Quad cores have four. All the cores are on the same chip they share the same memory and data path to the motherboard. A Dual core processor is basically 2 processors in 1, with some loss. A Quad core is 2 Dual core processors in 1 ,so a Quad core would be twice as fast as a Dual core, while a Dual core is twice as fast as a single core.
The "core" in a processor is the microprocessor inside of the CPU(Central Processing Unit). For example, if you have a Dual Core CPU then you have 2 microprocessors inside of the CPU, this allows you to do two things at once, as a microprocessor can only do one thing at a time the only exception to this is Multi-Threading which allows one core to do the work of multiple cores, but its not as fast as having multiple cores.
Depends which model, and whether you are talking about physcial cores or virtual cores, for example a processor can have two physical cores and two virtual cores and still be branded a "quad core" Apart from the bottom of the range i5 650, the rest are sold as "quad cores" although they don't have four physical cores.
