Time for a new computer

[Chivas]

The last thing you want is a Dell if they still use proprietary parts. You can build a much better computer, cheaper, and one that you can easily upgrade memory, cpu, and videocard, as the need arises. Cheaply extending the life of your computer.

I would build a system based on the "Intel Core i7 875K Quad Core LGA1156 2.93GHZ Hyperthreading 8MB Cache Unlocked Processor". Its is highly overclockable.
