CyberPowerPC - Unleash The Power

Hi looking to buy a new rig from cyber power after doing a little research have come up with a rig i like the look of but just wondering about this tech.

When building my rig using this site you have the option of adding a solid state disk to make use of this feature so just wondering if i were to select this would i need to do anything at home or would you guys get this up and running when you installed my os ( will be getting windows 7 64bit)

sorry for the nooby question its just this is a big investment for me and would rather get it right when having it built heh, also any advice on the setup i am thing of choosing would be helpful

cheers for the help going to go order it now, will listen to your tip about the ram but dont really want to upgrade that 7870 thing is when i started putting this build together a few days back it was only going to cost me £700 but this site has so much cool stuff on it i kept telling myself " only £30 more and i can get a even better version" my builds about £1000 now and i have to stop or my bank managers going to string me up lol

True, decent Sound starts at the Recon and Xonar DG.

Very good card, D2X is getting toward silly money and more for true Audiophiles. DX hits the price/performance nicely.
