Upgrading Old Alienware Area 51 7500 R5

[Stumpy622]

Hello Everyone! I am new to the forum and would like some help/advice on what i should/can do with the old PC. Here are the specs.
Processor type Intel Core 2 Extreme QX6700
Processor speed 2660.0 MHz
Primary Graphics Chipset EVGA GeForce 8800 GTX
Video Bus PCI Express-SLI
Video Memory Type DDR3
Optical Drive Speed 18.0
Optical Drive Type DVD±RW
Included Drives 3
It is currently lacking a hard drive but has everything else still in tact! I would like to be able to game a little on it if possible, if it would be better to start from scratch.
Thank you!

Also can i find a SSD that runs on the 3g/s speed set up for the motherboard?

So four slots have been taken up and you have 4GB of RAM? What is the frequency of the RAM?

 

[Stumpy622]

The computer is currently not running due to there being no hard drive. So i cannot check the frequency, and yes, the 4 slots are taken up. So first step is a hard drive that will work. Then everything else will be easier from there. I also have a water cooling system. Am I going to have to do anything with that? Replacing coolant?
Thanks!

Also I think 3GB/s SSD's have become pretty pricy and 6GB is the standard now. I'm sure the 6GB/s would be compatible except it wouldn't be as fast.

Ok! Perfect, Thank you! I will get those things together and start going. Should i leave the ram as is? Or would two 4gb's be an option.

6gb is enough for almost anything now so if you have four you should be alright!
